Engineering active sites in ternary CeO2-CuO-Mn3O4 heterointerface embedded in reduced graphene oxide for boosting water splitting activity

Scientific Reports, Journal Year: 2025, Volume and Issue: 15(1)

Published: Feb. 3, 2025

The rational design of highly efficient and stable bifunctional catalysts for overall water splitting is vitally important. In this study, to increase the active catalytic sites CeO2 electrochemical splitting, a ternary CeO2-CuO-Mn3O4 heterostructure, synthesized by coprecipitation method, loaded on reduced graphene oxide (rGO) nanosheets in different amounts produce CeO2-CuO-Mn3O4@rGO nanocomposites. It found that nanocomposites show higher electrocatalytic activity than unsupported samples, best observed when wieght ratio three times rGO. CeO2-CuO-Mn3O4@rGO(3:1) requires low overpotentials 130 270 mV hydrogen oxygen evolution reactions (HER OER) at current density 10 mA cm−2. Furthermore, material demonstrates large electrochemically surface area, charge transfer resistance, suitable kintics, high long-term stability both OER HER. Additionally, used as self-supported electrodes reaction, cell voltage 1.68 V obtained. This superior performance due to: (i) multi-metal strong synergistic effects; (ii) conductivity rGO, which faciliate favorable electron transfer; (iii) homogenous anchoring increases number available catalyst surface.

The potential of copper oxide nanoparticles in nanomedicine: A comprehensive review

Biotechnology Notes, Journal Year: 2024, Volume and Issue: 5, P. 80 - 99

Published: Jan. 1, 2024

Nanotechnology is a modern scientific discipline that uses nanoparticles of metals like copper, silver, gold, platinum, and zinc for various applications. Copper oxide (CuONPs) are effective in biomedical settings, such as killing bacteria, speeding up reactions, stopping cancer cells, coating surfaces. These inorganic nanostructures have longer shelf life than their organic counterparts chemically inert thermally stable. However, commercial synthesis NPs often involves harmful byproducts hazardous chemicals. Green CuONPs offers numerous benefits, including being clean, harmless, economical, environmentally friendly. Using naturally occurring organisms yeast, fungi, algae, plants can make more expected to be used nanomedicine due potent antimicrobial properties disinfecting agents infectious diseases. This comprehensive review looks evaluate research articles published the last ten years investigate antioxidant, anticancer, antibacterial, wound healing, dental application catalytic copper generated using biological processes. Utilising approach large-scale data analytics. toxic effects on vertebrates invertebrates raise concerns about use diagnostic therapeutic purposes. Therefore, biocompatibility non-toxicity crucial selecting clinical research.
