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

Multifaceted Cu 2 O with controlled crystal facet exposure was synthesized via a facile one-step method. It was found that photogenerated electrons prefer to accumulate on high index planes, while holes tend to migrate to {100} facets of a Cu 2 O polyhedron, leading to efficient charge separation and enhanced photocatalytic reforming of glucose.
