N2 - The photocatalytic characteristics of partially reduced TiO2 (TiO2-x) by plasma treatment and plasma-heated treatment were investigated in the visible-light region. For the visible-light photocatalytic activity of TiO2-x, plasmaheated treatment shows stronger than plasma treatment significantly. The TiO2-x by plasma-heated treatment shows broader red-shifted absorption bands than one by plasma treatment in the visible-light region. The surface color of TiO2-x by plasma treatment and plasma-heated treatment changed from white to sky blue, and to navy, respectively. After exposure to air, the surface color of TiO2-x changed from sky blue to white for plasma treatment and from navy to beige for plasma-heated treatment.
