Abstract
Here a facile hydrothermal method was developed to prepare heterogeneous photocatalyst constructed by decorating nanorod-assembled orbicular WO_3-0.5 H_2O on the surface of porous carbon nitride nanosheets. By integrating two martials with synergetic effect according to their bandgap structure, as-obtained catalyst exhibits well-suppressed recombination of the photoexcited carriers by formation of Z-scheme bandgap structure. It, together with the increased surface areas, contributes to the significantly improved photo-catalytic performance. As a result, the heterogeneous photocatalyst reveals a hydrogen generation rate of 3100 umol-g~(-1)-h~(-1) under visible light irradiation, accounting for an approximately 16 times higher than that of pristine graphite carbon nitride. Accordingly, as proposed strategy provides a new opportunity to explore advanced catalysts with superior properties for renewable energy utilization.
