ZnO Nanosheets with Atomically Thin ZnS Overlayers for Photocatalytic Water Splitting

ZnO nanosheets with atomically thin ZnS overlayers were engineered for highly-efficient water splitting, and the ZnS/ZnO/ZnS sandwich nanostructure demonstrates intensive light absorption, fast charge separation, long electron lifetime, and eventually the highest hydrogen production rate reported for oxide catalysts so far.
