| Zusammenfassung: | © 2018 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim. Efficient light harvesting and charge separation are of great importance in solar-energy conversion on photocatalysts. Herein, the synthesis of a novel hollow porous CdS photocatalyst with effectively restrained electron-hole recombination is reported. By using microporous zeolites as a host and a hard template, ultrasmall Pd and PdS nanoparticles can be anchored separately onto the inner and outer surfaces of a hollow CdS structure. The metallic Pd pulls the photoexcited electrons away from CdS while PdS pushes the holes for more thorough oxidation of the sacrificial agent. The final PdCdS/PdS product exhibits superior visible-light-driven photocatalytic H2 evolution rate of up to 144.8 mmol h-1 g-1 . This is among the highest values of all the reported CdS-based catalysts. This synthetic approach may be used to fabricate other highly efficient catalysts with spatially separated cocatalysts |
