Unidirectional suppression of hydrogen oxidation on oxidized platinum clusters

Abstract


  • Solar-driven water splitting to produce hydrogen may be an ideal solution for global energy

    and environment issues. Among the various photocatalytic systems, platinum has been

    widely used to co-catalyse the reduction of protons in water for hydrogen evolution. However,

    the undesirable hydrogen oxidation reaction can also be readily catalysed by metallic

    platinum, which limits the solar energy conversion efficiency in artificial photosynthesis. Here

    we report that the unidirectional suppression of hydrogen oxidation in photocatalytic water

    splitting can be fulfilled by controlling the valence state of platinum; this platinum-based

    cocatalyst in a higher oxidation state can act as an efficient hydrogen evolution site while

    suppressing the undesirable hydrogen back-oxidation. The findings in this work may pave the

    way for developing other high-efficientcy platinum-based catalysts for photocatalysis,

    photoelectrochemistry, fuel cells and water–gas shift reactions.
