Abstract

Graphene oxide (GO) is a 2D material that has various oxygen functional groups on its surface and edges. The existence of these clusters makes GO have enormous potential to be applied in various fields. Currently various methods have been developed to synthesize these materials including Liquid Phase Exfoliation (LPE) and Hummer's. This review will present the synthesis of Graphene oxide along with the results of its characterization using Fourier Transform Infra Red (FTIR), Raman Spectroscopy, and UV-Vis spectrophotometer. Literature results show that in FTIR the typical functional groups that will appear are the O-H, C=O, and C-O epoxy groups, on Raman spectroscopy it shows peaks of 1300-1400 cm-1 (D-band) and peaks of 1500-1600 cm-1 (G -band) and there is a maximum absorption peak value at a wavelength of 200-235 nm from the results of UV-Vis characterization Keywords: Graphene Oxide, Hummer’s, Liquid Phase Exfoliation, Raman Spectroscopy

Abstract

Nanoparticles of CaO (CaO-NP) are currently a frequently used material in research due to their excellent catalytic and antibacterial activities, low toxicity, abundant availability, and relatively affordable manufacturing cost. One of their applications is as a photocatalyst, commonly employed to degrade organic materials such as dyes. This review discusses the utilization of CaO nanoparticles as photocatalysts for both cationic and anionic organic dyes. Literature results indicate that CaO-NP can serve as a catalyst in the photocatalysis of dyes, whether they are cationic or anionic. The percentage of degradation achieved varies, ranging from as low as 60% to as high as 99.21%. These varying results are attributed to the different parameters used in the diverse photocatalysis processes. Keywords: CaO Nanoparticle, Organic Dye, Photocatalysis

Abstract

This review article aims to collect, compare and analyze the latest research on the synthesis and characterization of CaO nanoparticles from eggshells. CaO is a material in the form of white crystalline solids made from thermal decomposition of limestone or shells, which contains CaCO3 which has the potential to become CaO nanoparticles to be applied in various fields. Currently, various methods have been carried out to synthesize these materials, such as precipitation methods, hydrothermal methods, sol-gel methods, and so on. One of them is the calcination method. The calcination method itself is a commonly used thermal processing method involving heating at high temperatures. The advantages of the calcination method are that it is efficient, has a high level of purity, is economical and relatively simple and others. However, the calcination method itself has disadvantages, namely the process time is quite long, must be careful and can have a negative impact on the environment. In this review, we will discuss the synthesis of CaO nanoparticles characterized using X-Ray Diffraction (XRD), Fourier Transform InfraRed (FTIR), Scanning Electron Microscope (SEM), Transmission Electron Microscope (TEM). The literature results show that in XRD the main peak 2θ positions are 111 and 200 and the crystal size is 10-55 nm, in FTIR the functional groups that appear are the Ca-O stretch group and C-O stretch vibrations, in SEM and TEM the shape of the crystal. Keywords: Synthesis, CaO nanoparticles, Calcination

Abstract

This review article endeavours to comprehensively gather, compare, and scrutinize recent studies pertaining to the solvothermal synthesis of MOF-5 and its diverse applications. MOF-5 with the molecular formula Zn4O(BDC)3 which can be synthesized from a metal salt of zinc (Zn) with its organic ligands 1,4-benzene dicarboxylic acid (BDC) or terephthalic acid. In the last recent years, research on MOF-5 has continued to evolve and a variety of different synthesis methods have been tested. The synthesis process generally involves the use of polar organic solvents, such as N'N-diethylformamide (DEF) or N'N-dimethylformamide (DMF) at high temperatures and pressures. The solvothermal method is the most frequently used technique and allows good control over crystal size, morphology, and surface area. Factors such as solvent, temperature, reaction time, and metal/ligand ratio affect the properties of the resulting MOF-5 crystal. MOF- 5 is widely applied as a drug carrier material in drug delivery systems. MOF-5 has a high surface area that supports drug loading efficiency and significant hydrogen storage capacity. In addition, MOF-5's ability to release guest molecules in a controlled manner makes it an attractive choice for continuous applications. MOF-5 is also used in a variety of other applications including liquid and gas separation, catalysis, and adsorption. Research on modifying the structure of MOF-5 continues to evolve to meet the needs of increasingly diverse applications. Keywords : Synthesis, Terephtalic Acid, MOF-5, Solvothermal
