Doping Cr into perfect TiO2 (110) surface can create the new active surface state different from that of oxygen defect surface ,AM and transition metals deposited TiO2 (110) surface. Its active surface state is the Cr 3d occupied state near EF and the value of band-gap drop from 3.13eV to 1.16eV, so photocatalysis reaction can perform in visual light area after doping Cr into perfect TiO2 (110) surface.
