Abstract:90% exposing single crystal TiO2 (001), (101) and (010) were synthesized by hydrothermal method, and noble metal Ag was loaded on TiO2 single facets through photodeposition. The crystal-facet effect for Ag-loading was studied. It was found that at the same synthesis condition, the size of Ag particles loaded on different single facet was different which was Ag/TiO2-101
