Synthesis of Ag-Ag2O nanoparticles using Ageratum conyzoides leaf extract for the catalytic reduction of nitrobenzene and methylene blue and antibacterial applications

The 4-nitrophenol (4-NP) and methylene blue (MB) are commonly used in many industries and remain in the industrial effluent. They have an adverse effect on the environment if not treated properly. Therefore, it is essential to develop a convenient method to remove such toxic chemicals from wastewater. Here, Ag/Ag2O nanoparticles (NPs) were prepared from AgNO3 […]

Synthesis of a thin film of CuO/MgO/PVC nanocomposites for Photocatalytic applications

This study investigates the effect of a combination of copper and magnesium oxide nanoparticles embedded in a Polyvinyl chloride (PVC) matrix on photocatalytic activity. A thin film of CuO/MgO/PVC nanocomposites (NCs) was synthesized using the sol-gel route. Different weight percentages of CuO/MgO nanocomposites (5% and 15%) incorporated in the PVC matrix were deposited on glass […]

The most important parameters that affect the photocatalytic activity of ZnO nanostructures against organic dyes: A Review

Organic dyes are among the main sources of water pollution that cause serious health problems for living organisms. Removing dye pollution from water sources is important because of its high toxicity, so it has attracted the interest of researchers. Heterogeneous photocatalysis based on ZnO is one of the most important methods of pollution treatment. The […]

Catalytic oxidative desulfurization of dibenzothiophene by heterogeneous M2+/Al-layered double hydroxide (M2+ = Zn, Mg, Ni) modified zinc oxide

In this study, the preparation of layered double hydroxide-metal oxide (ZnAl-ZnO, MgAl-ZnO, and NiAl-ZnO) was successful. The characterization of the catalyst used XRD, FTIR, and SEM analysis. The catalyst shows high oxidative desulfurization of dibenzothiophene. The percentage conversion of dibenzothiophene on ZnAl-ZnO, MgAl-ZnO, and NiAl-ZnO was 99.38%, 99.34%, and 99.90%, respectively. The acidities of ZnAl-ZnO, […]

Mild Synthesis, Characterization, and Application of some Polythioester Polymers Catalyzed by Cetrimide Ionic Liquid as a Green and Eco-Friendly Phase-Transfer Catalyst

In this research, we develop and prepare some of the polymers based on polythioesters using cetrimide as an ionic liquid and phase transfer catalyst. All of the polymers were prepared through the reaction of 5,5'-methylenebis (1,3,4-oxadiazole-2-thiol) with five types of diacyl chloride derivatives in the presence of cetrimide as phase transfer catalyst in the mixture […]

Effect of surfactant on structural and optical properties of V2O5 nanocrystals as a potential catalyst for photodegradation

An anionic, cationic, and non-ionic surfactant-assisted wet chemical method was used to synthesize vanadium pentoxide (V2O5) nanocrystals. XRD, FESEM, EDX, FTIR, UV-Vis, and PL techniques were used to characterize the V2O5 nanocrystals. The formation of V2O5 nanocrystals is confirmed by the experimental results. The addition of surfactants had a significant effect on the morphology, crystallinity, […]

Investigation of Geological Diversity Based on the Degree of Sensitivity and the Amount of Equilibrium and Resilience of the Geosystem (Case study: The Eastern Kopet-Dagh Zone)

Geomorphological principles show that the earth's surface is not fixed and changes over time. The physical elements of the earth's surface, from microscopic components such as minerals to macroscopic phenomena such as landforms, are all part of geodiversity. Landform equilibrium and resilience are related to the resistance to the erosion pattern. In other words, morphogenic […]

Establishment of the Luoping Biota National Geopark in Yunnan, China

Geoparks in China have been a great success story, with 284 national geoparks and 41 of them accorded UNESCO international status, the highest number for any country in the world. We track the progress of one of the geoparks, Luoping Biota National Geopark in Yunnan Province, from initial plans after its discovery as a key […]
