3D mesoporous architectures of CdS and Pt nanocrystals are demonstrated as highly effective catalysts for the hydrogen evolution reaction (HER). Photocatalytic measurements coupled with spectroscopic studies suggest that deposition of ultrasmall Pt nanoparticles enhances the H2-production activity because of variations in the band-edge positions and electron donor density of CdS nanocrystals.
