Summary: In this study, an efficient photoelectrode, rGO-CuO/Cu, was prepared using a facile one-pot hydrothermal approach. The best performance was observed in the photoelectrode synthesized in 3 hours of hydrothermal reaction, with higher photocurrent density and charge carrier density. Optimizing the reaction time led to more surface area available for effective charge transfer separation, improving the overall performance of the photoelectrode in solar-to-hydrogen generation.

Summary: Supercapacitors (SC) have great potential as energy storage technologies, thanks to their high conductivity and large surface area with porosity. In this study, researchers report on a one-step hydrothermal technique to synthesize pristine and heterostructure metal sulfide with reduced graphene oxide (rGO) based nanocomposite for supercapacitor applications. The resulting nanocomposite electrode showed excellent capacitance retention and cycling stability, with a specific capacitance (Cs) of 1480 F/g at a current density of 3 mA g-1 and a capacitance retention rate of 92% after 3000 cycles. This research work is a step towards improving the performance of supercapacitor devices using Ni-Mo-S and rGO based nanocomposite electrodes.
