Abstract

The CdS and Pt NPs have been homogeneously anchored and highly dispersed into the mesopore channels of hierarchically porous zeolite Beta by a facile successional two-step pore modification technology. A highly efficient and stable H₂ evolution of 3.09mmol/h/g_catalyst has been successfully achieved by using the prepared novel catalyst under sunlight irradiation. It is believed that the highly dispersive CdS and Pt NPs and the synergetic catalytic effect between them, as well as the interaction between CdS species and zeolite matrix, contribute to the enhanced separation and transfer of photoelectrons and holes, and therefore improving its electrochemical properties and H₂ evolution rate. Besides, and this novel hierarchical pore structure of zeolite Beta serving as a host can effectively protect CdS NPs from photocorrosion, thus exhibiting high stability in the catalytic system.
