摘要：
Facet-selective growth: Regular ZnO/TiO2 heterojunctions have been successfully synthesized using a facile hydrothermal technique (see figure). Due to the interfacial lattice matching, wurtzite ZnO can only grow on the eight {101} facets of the anatase TiO2 single crystals, while the other two {001} facets are untouched. The as-prepared regular ZnO/TiO 2 heterojunctions exhibited enhanced photocatalytic generation of .OH radicals and enhanced photodegradation of methyl orange when irradiated with UV light.
