<i>In situ</i> growth of M-{001}TiO₂/Ti photoelectrodes: synergetic dominant {001} facets and ratio-optimal surface junctions for the effective oxidation of environmental pollutants

Abstract

We report a novel {001}TiO₂/Ti photoelectrode by directly constructing "mirror-like" TiO₂ microspheres on a Ti foil substrate (M-{001}TiO₂/Ti). It presents highly enhanced PEC oxidation capability of DMP wastewater, which is mainly attributed to the significant synergetic effects of high exposure of {001} facets and equivalent {001}/{101} facet junctions.
