Solar energy-driven photocatalysis, such as photocatalytic H2O splitting to produce H-2, is a promising strategy to solve the energy and environmental crises. Applications of zeolites, which have been widely used in conventional thermal-driven catalysis, in photocatalysis are still limited, due to their low photocatalytic efficiencies. Herein, we fabricated a porous lantern-like MFI zeolite composed of 2D nanosheets (NL-MFI) and used NL-MFI to support Pt and CdS nanoparticles to form a CdS/Pt/NL-MFI photocatalyst. During water splitting under irradiation of visible light, CdS/Pt/NL-MFI exhibits a H-2 evolution rate as high as 2152.7 mu mol h(-1), with an apparent quantum efficiency of 39.4%. This is significantly enhanced, as compared with that by using commercial MFI zeolite supported CdS and Pt nanoparticles (1079.3 mu mol h(-1)) and that by using Pt/CdS without the NL-MFI zeolite (515.0 mu mol h(-1)). The NL-MFI zeolite support promotes the absorption of visible light, the separation of photogenerated electron-hole pairs and the interaction of water molecules with the photocatalyst. This could be the origin of the enhanced photocatalytic efficiency of CdS/Pt/NLMFI. The results of the present work are helpful to fabricate zeolite-based photocatalysts for efficient solar energy-driven photocatalysis.
