Summary: Electrochemical water splitting is a promising pathway for efficient hydrogen evolution, and the development of effective catalysts or electrocatalysts is crucial. In this study, a graphene-modified nanoparticle catalyst, rGO-TiO2-NiO-ZnO, was evaluated for hydrogen evolution reaction (HER). The presence of rGO as an electron collector and transporter significantly improved the electrocatalytic H-2 production rate, and a current density of 10 mA/cm(2) was achieved at a reduced working potential of 365 mV for the nanocomposite. The electronic coupling effect between the nanoparticle components at the interface contributed to the catalytic activity of the nanoparticle for HER.

Summary: In this study, we prepared a copper nanofibril assembly using thermal oxidation and electrochemical reduction processes. The resulting structure exhibited excellent glucose detection ability with a high sensitivity, low detection limit, wider linear range, and long-term stability. The enhanced glucose sensing ability of the copper nanofibril structure can be attributed to its morphology, origin of the Cu (111) facet, and formation of a stable oxide layer. This structure showed no response to other interfering substances such as chloride ion, dopamine, ascorbic acid, and uric acid, making it a promising candidate for glucose sensing applications.
