12/11/2023 0 Comments Cuo oxygen charge![]() The obtained results indicate the CuO and Ag/CuO NPs may further use in wastewater treatment and biomedical applications.Ībrile MG, Fiasconaro ML, Lovato ME (2020) Optimization of Reactive Blue 19 dye removal using ozone and ozone/UV employing response surface methodology. There is no secondary product formation and rich activated electrons. ![]() The AOP photocatalyst is widely used to remove the toxicity of wastewater. The advanced oxidation process would increase the electron–hole pair activity and reactive oxygen species (ROS) formation. The pseudo-first-order kinetics were found to increase the rate of dye degradation by adding Ag ions to the CuO surface. The metallic Ag-doped with CuO NPs improves the catalytic compared to pure CuO NPs. The photocatalytic activity of CuO and Ag/CuO NPs were analyzed against Rhodamine B (Rh-B) dye under visible light irradiation. aureus) and Gram-negative ( Escherichia coli- E. ![]() The biosynthesized CuO and Ag/CuO NPs were performed against Gram-positive ( Staphylococcus aureus- S. Mostly, they are resolved by nanoparticles. Occasionally, contagious diseases shake the world and affected human healthiness because of their pathogenic activity. Copper and silver metals and oxygen valencies and binding energies were examined by XPS. The FTIR analysis was performed to confirm the possible functional groups of plant extract involved in chemical reduction and bondings. The EDX analysis analyzed the composition of the elements in the synthesized NPs. SEM and TEM analyses characterized the morphology and size variation of the CuO and Ag/CuO NPs. The NPs crystalline nature and size were analyzed by XRD. CuO bandgap is higher than the Ag/CuO NPs (∆Eg = 0.55 eV) reveals the Ag/CuO NPs have remarkable optical and catalytic applications. The bandgap decreasing is informed that the results have opted in the optical and catalytical applications. The Ag + and Cu + reduction were confirmed through the surface plasmon resonance in the DRS spectrum. The purpose of plant extract is to reduce the negative impact of the synthesis method and its derivatives. The plant extract acts as a reducing and stabilizing agent. In the present work, CuO and Ag/CuO nanoparticles (NPs) were synthesized by Cyperus pangorei extract using the co-precipitation method. The nano-based particles have the potency to overcome water contamination. Water contamination is a critical and severe issue all over the world.
