The metal type selectivity for photocatalytic reactions of semiconductor-metal hybrid nanoparticle

Semiconductor-metal hybrid nanoparticles (HNPs) are promising photocatalysts for redox reactions, including H₂ generation and reactive oxygen species (ROS) formation. Herein, we study the effect of the metal co-catalyst type on the light-induced ROS (^•O₂^-, H₂O₂ and ^•OH) and H₂ formation. Understanding the contribution of the different nanocrystal features on their photocatalytic activity could allow to optimize their design as catalysts for various ROS-driven applications, including light-induced radical-polymerization, and in environmental and biomedical scenarios.
