Green Synthesis and Photocatalytic Applications of Cobalt Oxide Nanomaterials
This community focuses on the creation of cobalt oxide nanoparticles and thin films using plant-based extraction methods, primarily to evaluate their ability to degrade organic pollutants and their antibacterial properties.
The research centers on the synthesis of cobalt oxide (Co3O4) nanoparticles, often utilizing plant extracts such as turmeric, guava, or muscadine for green fabrication. A significant portion of the work investigates the photocatalytic degradation of dyes like methylene blue and the antibacterial activity of these nanomaterials. Other recurring themes include the structural and optical characterization of thin films, the thermal decomposition of cobalt precursors, and the development of electrochemical sensors. While nickel oxide and other transition metal oxides appear, cobalt remains the dominant material, with applications ranging from environmental remediation to biomedical sensing.
The community is most heavily concentrated in cobalt research, accounting for 728 papers, though this represents only 1.7% of all tracked cobalt literature. It also appears in research on yttrium, lanthanum, and praseodymium, with smaller shares of the total output for those elements.
The group comprises 1,657 papers, with the highest publication volumes in Thermochimica Acta, Journal of Alloys and Compounds, and Journal of Thermal Analysis and Calorimetry.
Recent work continues to explore the synthesis of cobalt oxide nanostructures via microwave-assisted and plant-mediated methods, alongside studies on their electrochemical sensing capabilities and biological interactions.
