Green Synthesis of Metal Oxide Nanoparticles for Photocatalysis and Antibacterial Use
This community focuses on the production of metal oxide nanoparticles, primarily using plant-based extracts, to create materials that degrade organic pollutants under light and inhibit bacterial growth.
The research centers on zinc oxide, with significant work on copper oxide, titanium dioxide, and iron oxide. A dominant method is "green synthesis," where leaf extracts serve as reducing and stabilizing agents to form nanoparticles. These materials are frequently tested for photocatalytic activity, specifically the degradation of dyes like methylene blue and other organic contaminants in wastewater. Antibacterial and antimicrobial properties are also a primary application area. The work includes the fabrication of thin films and nanocomposites, often involving doping to enhance structural and optical properties.
The largest share of the community's output is found in zinc research, accounting for 24.6% of all zinc research, and 21,487 papers here. Copper research contributes 8.6% of its total output, and titanium research contributes 1.8%.
The community comprises 37,723 papers, publishing most frequently in Ceramics International, Inorganic Chemistry Communications, and the International Journal of Biological Macromolecules.
Recent work continues to examine the photocatalytic treatment of textile dyes and the antibacterial mechanisms of zinc oxide nanoparticles, alongside studies on gas sensing performance and the synthesis of iron oxide nanoparticles using specific plant extracts.
