Abstract

A novel p-n heterojunction photocatalyst composed of porous NiO nanosheet (NSs) and CdS nanocrystal (NCs) was successfully synthesized by a facile hydrothermal route. In the heteroarchitecture, porous NiO NSs are uniformly decorated with CdS NCs. CdS NCs/NiO NSs heterojunction photocatalyst exhibits enhanced photocatalytic activity for hydrogen generation at a rate of 45.3 mmol h⁻¹ g⁻¹ (AQE 55.3 %), which is approximately 28 times higher than pure CdS and pure NCs under visible light irradiation. The enhanced visible-light photocatalytic activity of CdS NCs/NiO NSs heterojunction could be attributed to its enhanced absorption in the visible region and the low recombination rate of the electron-hole pairs due to the tight heterojunction formed between the porous NiO NSs and CdS NCs.

期刊介绍： Composites Communications (Compos. Commun.) is a peer-reviewed journal publishing short communications and letters on the latest advances in composites science and technology. With a rapid review and publication process, its goal is to disseminate new knowledge promptly within the composites community. The journal welcomes manuscripts presenting creative concepts and new findings in design, state-of-the-art approaches in processing, synthesis, characterization, and mechanics modeling. In addition to traditional fiber-/particulate-reinforced engineering composites, it encourages submissions on composites with exceptional physical, mechanical, and fracture properties, as well as those with unique functions and significant application potential. This includes biomimetic and bio-inspired composites for biomedical applications, functional nano-composites for thermal management and energy applications, and composites designed for extreme service environments.
