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

Abstract

Terephthalic acid is an important ligand in the manufacture of MOF-5 which has been obtained from the depolymerization of PET (polyethylene terephthalate) recycled from PET plastic waste. Depolymerization of PET polymers into terephthalic acid ligands (linkers) is carried out using the acid-base hydrolysis method at room temperature using H2SO4 and NaOH. The yield was obtained at 40.95% (8.19 grams). PET monomers in the form of terephthalic acid were then tested by Thin Layer Chromatography (TLC) using n-hexane and ethyl acetate solvents (1:2). The TLC results showed the same stain spot between depolymerized terephthalic acid and commercial terephthalic acid. Depolymerized terephthalic acid and commercial terephthalic acid were then analyzed using Fourier Transform Infrared (FTIR) which showed the presence of functional groups C=O, C-O, C-H, and O-H and analyzed with a UV-Visible Spectrophotometer and obtained a maximum wavelength in both materials of 306 nm. Keywords: Terephthalic Acid, depolymerization, polyethylene terephthalate

Abstract

Adsorption of Rhodamin B Dye with Fe3O4-Coffee Grounds Composite has been carried out. The purpose of this study is to determine the optimum time, optimum pH, maximum adsorption capacity and type of adsorption isotherm in rhodamin B dye with Fe3O4-Coffee grounds composite. The first stage of making Fe3O4-Coffee grounds composite using the coprecipitation method with FeCl3‧6H2O and Fe(SO4)2‧7H2O was weighed with a molar ratio of 3:2, then combined with coffee grounds. The results showed that the optimum time was obtained at 20 minutes, at the optimum pH at pH 10, and the maximum adsorption capacity obtained was 40.19 mg/g. The results of the determination of the type of isoterm in the adsorption of rhodamin b were obtained by the type of Langmuir isoterm.

Abstract

This review article discusses the effectiveness of composite synthesis methods for ZIF-8 with metal oxides and their applications in various fields. ZIF-8 is a popular metal-organic framework due to its stability; however, it has limitations, such as low conductivity, limited catalytic activity, and poor recyclability. To address these issues, various methods for synthesizing ZIF-8-metal oxide composites have been developed in recent years. These composites demonstrate significant potential to enhance performance in applications like photocatalysis and energy storage, as metal oxide-based materials can provide higher energy density and improved conductivity. This review presents a recent comparison of different synthesis methods to provide further insights into developing these materials for industrial applications. Keywords : Metal Oxide, ZIF-8, ZIF-8 Composite Synthesis

Abstract

Mini-review this discusses recent studies related to the synthesis of ZIF-8 with variations of deprotonation agents and their applications. ZIF-8 with the molecular formula C8H12N4Zn is generally synthesized from Zn(NO3)2.6H2O (zinc nitrate hexahydrate) or other metal salts as a central metal source bonded to C4H6N2 (2-methylimidazole) as an organic compound and water as a solvent. In recent years, research on ZIF-8 has continued to grow with various modifications made by researchers. The synthesis process generally involves the use of expensive and flammable organic solvents in the synthesis medium and results in harmful effects to the environment due to its toxic nature. This raises urgency in ZIF-8 synthesis innovation, one of which is with a green synthesis method using water-based solvents. In the synthesis of ZIF-8, deprotonation agents such as NH4OH, TEA, NAOH and others are often used. The use of this deprotonation agent allows the formation of ZIF-8 with good crystal size, surface area, pore volume and % yield from ZIF-8 produced both synthetic ZIF-8 can be used in various fields such as antibiotic adsorption, catalysts, and separation. Keywords : synthesis, deprotonation, ZIF-8, antibiotic

Abstract

Photocatalytic degradation is a widely studied method for reducing the concentration of organic pollutants. This technique has proven effective in breaking down various organic compounds, including dyes, pharmaceuticals, and pesticides. Metal-Organic Frameworks (MOFs) represent a promising class of materials for photocatalytic degradation due to their favorable catalytic properties, such as high porosity and large surface area. Additionally, MOFs offer structural tunability, allowing their properties to be tailored for specific applications. This review discusses the structural characteristics, photocatalytic mechanisms, synthesis strategies, current applications, and the future prospects and challenges of Zn-based MOFs in the photocatalytic degradation of organic pollutants.   Keywords: Metal-Organic Frameworks, Zinc, Photocatalytic Degradation
