Abstract

A new trinuclear Zn (II) complex, [Zn3(L1)4(L2)2(CH3COO)2] (1) (HL1 = 6-phenylpyridine-2-carboxylic acid, L2 = bis(4-pyridyl)amine) has been synthesized by 6-phenylpyridine-2-carboxylic acid, NaOH, bis(4-pyridyl)amine and Zn(CH3COO)2•2H2O. The complex 1 has also been structural characterized by elemental analysis and single crystal X-ray diffraction. The results reveals that complex 1 is made up of three Zn(II) ions, four L1 ligands, two L2 ligands and two CH3COO- anions. In 1, both Zn1 ion and Zn1a ion are five-coordinated with two O atoms from two different L1 ligands, two N atoms from two different L1 ligands, and one N atoms from bis(4-pyridyl)amine ligand, respectively, and forms a distorted trigonal biyramid geometry. And Zn2 ion is four-coordinated with two O atoms from two different CH3COO− anions and two N atoms from two different L2 ligands, forming a distorted tetrahedral geometry. Complex 1 displays a 3D network structure by the intermolecular N−H···O hydrogen bonds. The catalytic performance for oxidation of benzyl alcohol with O2 was studied under mild reaction conditions using complex 1 as catalyst. The results demonstrated that the catalysts were very active, and the yield of benzaldehyde was 50.8% at 90 °C with THF as solvent under 0.5 MPa O2 within 3 h.

Abstract

An amine-functionalized multiwalled carbon nanotube (MWCNT) was prepared for use as a basic heterogeneous catalyst for the conversion of Cocos nucifera (coconut) oil and Hibiscus cannabinus (kenaf) oil to biodiesel. The 3-aminopropyltrimethoxysilane (3-APTMS) was chosen to form an amine-reactive surface to bind with hydroxyl (−OH) and carboxyl (−COOH) groups of oxidized MWCNT. Silanization took place using a green surface modification method in which supercritical carbon dioxide fluid was utilized under the following conditions: 55 °C, 9 MPa, and 1 h. The synthesized catalyst was characterized using Thermogravimetric analysis (TGA), Fourier transform infrared (FTIR), Field emission scanning electron microscopy–energy dispersive x-ray (FESEM-EDX), Time-of-flight secondary ion mass spectrometry (TOF-SIMS), X-ray powder diffraction (XRD), and Brunauer–Emmett-Teller (BET). Transesterification of coconut oil using 10 wt% NH2-MWCNT catalyst (3 wt% APTMS), 12:1 molar ratio of methanol and oil at 63 °C for 1 h resulted in a >95% conversion. On the other hand, the same catalyst was used in the transesterification of kenaf oil, and formation of ammonium carboxylated salt was observed. The effects of temperature, pressure, and silane concentration on surface modification of MWCNT were evaluated in terms of the catalyst’s basic site density and fatty acid methyl ester conversion. The results indicate that reaction temperature and silane concentration had the most significant effects. Copyright © 2022 by Authors, Published by BCREC Group.

Abstract

The present study includes synthesis of CdO thin film by simple and cost effective chemical bath deposition method. Cadmium monochloroaceatate were used for preparation of CdO thin film.  The structural, optical properties of CdO thin film were investigated with the help of X-ray diffraction (XRD) and UV-Vis NIR double beam spectrometry. The XRD studies revealed that annealed thin film shows crystalline in nature having 48.4 nm in size. The optical band gap of thin film was found to be 2.13 eV. Scanning Electron Microscopy (SEM) images shows sphere like structure which is closely arranged with each other. The presence of functional group was confirmed by Fourier Transform Infra Red (FTIR). Brunauer–Emmett–Teller (BET) surface area analysis confirm formation of a mesoporous CdO with 6.01 m2/g surface area and 31.96 nm average pore diameter. The photocatalytic activity of prepared thin film was checked by using Rhodamine-B as a model dye under natural sunlight and found to be 48%. Copyright © 2022 by Authors, Published by BCREC Group.

Abstract

Hydrogen is considered a future energy carrier for clean and sustainable technology. Photocatalytic reforming of methanol produced hydrogen using water and energy from sunlight. This study reported enhanced activity of TiO2 without metal co-catalyst for hydrogen production following H2O2 exfoliation. TiO2 was transformed into peroxo-titania species on the outer layer of the particles, resulting in surface exfoliation. The exfoliation reduced TiO2 crystallite sizes enhanced the surface hydroxyl group and reduced the band gap to 3.0 eV. Hydrogen production from methanol-water mixtures on the TiO2 after four consecutive exfoliations was measured at 300 µmol, significantly higher than the fresh TiO2 (50 µmol).  H2O2 exfoliated TiO2 reduced the pathway for charge migration to the surface.  A high concentration of surface hydroxyl group trapped the charge carriers for efficient hydrogen production.

Abstract

In this study, a facile low-temperature hydrothermal method was applied for the synthesis of bismuth subcarbonate nanoplates (Bi2O2CO3). The material was then characterized by FTIR, XRD, SEM, BET, and TGA. The applicability of Bi2O2CO3 was evaluated via the treatment of methyl blue (MB) in water by adsorption and photocatalytic degradation. The experiment results with different pH from 2 to 12 indicate that the pH of the solution affected the surface charge of the synthesized Bi2O2CO3, thus having strong effects on the adsorption and photocatalytic degradation abilities of Bi2O2CO3 for MB removal. In adsorption tests, pH 6–7 is the most suitable condition for the adsorption of Bi2O2CO3. In photocatalytic tests, Bi2O2CO3 had the highest and lowest efficiencies of 64.19% (pH 5) and 17.59% (pH 2), respectively, under UV irradiation for 300 min.

Abstract

Since alkynyl-arylamines are widely used in the chemical industry as pre products, a method of catalytic synthesis of problematic substituted quinolines from aromatic amines containing octadienal substituents has been developed. For this purpose, the processes of N-2,7-octa-dienyl anilines cyclisation under the action of transition metal complexes and telomerisation of arylamines with butadiene in the presence of palladium complexes were studied. Suppose N-2,7-octa-dienyl anilines are synthesised by telomerisation of arylamines with butadiene in the presence of palladium complexes. In that case, the cyclisation process is carried out in the presence of catalytic amounts of Pd(II) complex with dimethyl sulfoxide or nitrobenzene. The conducted research made it possible to study the opportunity of obtaining in one stage aromatic amines substituted in the nucleus by the reaction of butadiene with arylamines in the presence of palladium complexes. The research proved the principal possibility of obtaining ortho-substituted naphthylamines from butadiene and corresponding naphthylamines in one stage. A catalytic method for the synthesis of problematic substituted quinolines in the presence of palladium complexes has been developed. It has been established that the cyclisation of N-octadienyl-arylamines into quinolines proceeds through the stage of Kleisen amino rearrangement. N-2,7-octa-dienyl anilines and their derivatives can be widely used in the paint, pharmaceutical and chemical industries. Quinoline alkenylene derivatives can be used to produce unique polymer materials, hardeners, stabilisers, extractants, sorbing agents, catalysts for the synthesis of polyurethanes, biologically active substances and their analogues. They are pre-products in synthesising alkaloids, medicines and products used in agriculture. Copyright © 2022 by Authors, Published by BCREC Group.

Abstract

In ethanol-water (v:v = 1:1), a new Ni(II) complex, [Ni(L)2(H2O)2] (1) (HL = 6-phenylpyridine-2-carboxylic acid) was synthesized using 6-phenylpyridine-2-carboxylic acid, NaOH and Ni(CH3COO)2.4H2O. The structure of complex 1 has been determined by elemental analysis and single crystal X-ray diffraction. The single crystal analysis shows that complex 1 contains one Ni(II) ion, two L ligands and  two coordinated water molecules. In 1, the Ni(II) ion is six-coordinated to two O atoms and two N atoms from L ligands and two O atoms from coordinated water molecules, respectively, which form a distorted octahedral coordination geometry. The whole unit of complex 1 is interconnected to each other through intermolecular N−H•••O hydrogen bonds involving oxygen atom of coordinated water molecule and the oxygen atoms of  L ligand to form 1D molecular architecture. The catalytic activity of complex 1 for oxidation of benzyl alcohol with O2 was investigated. The complex 1 shows good catalytic performance for the oxidation of benzyl alcohol, the benzyl alcohol conversion, benzaldehyde selectivity, and benzaldehyde yield were 49.1%, 92.0%, and 45.2%, respectively, at 90 °C under 0.7 Mpa O2 for 2 h. Moreover, complex 1 could be recovered easily by centrifugation and used repetitively for at least four times. Copyright © 2022 by Authors, Published by BCREC Group.

Abstract

The hazardous toxicity of dye materials, even in low concentrations, harms ecological systems. It releases a large number of contaminants into the water, resulting as waste water. Dyes prevent the process of photosynthesis by obstructing light passage, lowers the oxygen levels dissolved in the water. Also, a good number of the dyes and heavy metals are carcinogenic and mutagenic to human beings. Heterogeneous photocatalysis is a promising technology for removing organic, inorganic, and microbial pollutants from water and wastewater. It is preferable to other conventional wastewater treatment approaches due to its benefit, such as low cost, environmental friendliness, ability to proceed at ambient temperature and pressure conditions, and to completely degrade pollutants into environmentally safe products with suitable measures. The titanium oxide (TiO2) is one of the most promising material that has gained enormous importance in the field of energy and environmental applications. The unique physicochemical properties of TiO2 make it one of the best candidates among existing photocatalysts. This review provides an overview of strategies employed to augment its catalytic performance as well as the impact of different operational parameters on the removal proficiency of various organic and inorganic pollutants in water and wastewater treatment.

Abstract

Studies of LDH materials to be applied as photocatalyst for dye pollutant degradation have been developed. These interesting efforts are inseparable from the investigation of degradation performance and competitive synthetic methods. Composites based on Zn/Al and Mg/Al layered double hydroxides (LDHs) with ZnO and TiO2 were prepared by coprecipitation-impregnation method following by calcination at 300 °C to forms Zn/Al-ZnO, Mg/Al-ZnO, Zn/Al-TiO2, and Mg/Al-TiO2. Composites were characterized by XRD, FTIR, SEM and UV-DRS. Photodegradation of malachite green (MG) was carried out, after optimization of pH, catalyst loading and contact time in batch system under UV irradiation. XRD and spectroscopic data shows composites were successfully formed indicated by formation of both pristine materials. Degradation of malachite green showed that composites as photocatalyst have higher catalytic activity than pristine LDHs. LDH-ZnO composite have better activity, energy band gap and degradation reusability than LDH-TiO2. The Zn/Al-ZnO and Zn/Al-TiO2 composites degraded 97.1% and 96.3% MG, whereas the Mg/Al-ZnO and Mg/Al-TiO2 composites were able to degrade 99.8% and 98.6% MG, respectively.
