Development of Visible-Light-Driven Rh-TiO2-CeO2 Hybrid Photocatalysts for Hydrogen Production

Abstract

Visible-light-driven hydrogen production through photocatalysis has attracted enormous interest owing to its great potential to address energy and environmental issues. However, photocatalysis possesses several limitations to overcome for practical applications, such as low light absorption efficiency, rapid charge recombination, and poor stability of photocatalysts. Here, the preparation of efficient noble metal-semiconductor hybrid photocatalysts for photocatalytic hydrogen production is presented. The prepared ternary Rh-TiO2-CeO2 hybrid photocatalysts exhibited excellent photocatalytic performance toward the hydrogen production reaction compared with their counterparts, ascribed to the synergistic combination of Rh, TiO2, and CeO2.
