Photocatalytic reforming of glucose under visible light over morphology controlled Cu_2O: efficient charge separation by crystal facet engineeringf

摘要

Multifaceted Cu_2O with controlled crystal facet exposure was synthesized via a facile one-step method. It was found that photo-generated electrons prefer to accumulate on high index planes, while holes tend to migrate to {100} facets of a Cu_2O polyhedron, leading to efficient charge separation and enhanced photocatalytic reforming of glucose.
