Electron Donor‐Specific Surface Interactions Promote the Photocatalytic Activity of Metal‐Semiconductor Nanohybrids Small (IF 13.3) Pub Date : 2024-04-18 Soenke Wengler‐Rust, Yannic U. Staechelin, Holger Lange, Horst Weller
In the past two decades, the application of colloidal semiconductor‐metal nanoparticles (NPs) as photocatalysts for the hydrogen generation from water has been extensively studied. The present body of literature studies agrees that the photocatalytic yield strongly depends on the electron donating agent (EDA) added for scavenging the photogenerated holes. The highest reported hydrogen production rates
