Understanding the mechanism of hydrogen (H) formation from the conversion of water (HO) and renewables on TiOsurfaces with cocatalysts via either photocatalysis or other catalytic processes is of significant importance to the successful design of efficient catalysts. Herein, we have investigated Hproduction from HO, CHOH, and CHOH on a Pt cluster covered rutile (R)-TiO(110) surface (Pt/R-TiO(110)) to address the mechanism of Hproduction. Experimental results demonstrate that surface adsorbates not only help H atom diffusion on Pt/R-TiO(110) but also take part in Hproduction directly. Further density functional theory (DFT) calculations suggest that Hproduction on Pt/R-TiO(110) occurs via a synergistic catalysis process between Pt clusters and interfacial adsorbates rather than a recombination reaction of H atoms on Pt clusters. This work provides new insight into Hproduction from HO and renewables with Pt/TiOcatalysts, which may be applicable to Hproduction on other Pt cluster deposited metal oxide catalysts.
