| Abstract |
Recently, photocatalysts comprising active sunlight‐harvesting photo‐absorbers and stable metal co‐catalysts have attracted significant attention. However, the size, clean surface, and highly dispersed nature of the metal co‐catalysts are crucial factors to affect catalytic performance and reaction rate. Nevertheless, most of the available metal nanocrystals have been synthesized by complicated procedures using harmful organic templates and stabilizers with difficulty and high cost. To overcome these problems, in this study, the pulsed laser ablation in liquid approach was applied to generate palladium and bimetallic palladium–platinum nanoparticles with an average size and distribution by adjusting the laser wavelength and fluence. They showed significantly improved amount of hydrogen evolution than that obtained by using bare CdS nanorods and several other noble‐metal co‐catalysts deposited on CdS . This proposed strategy is thought to open new avenues for the design of advanced photocatalytic materials for efficient solar‐driven production of hydrogen. |
