Rational Band Gap Engineering of WO3 Photocatalyst for Visible light Water Splitting

A band better than the Beatles? Tungsten oxide doping by hafnium induces a shift of the valence and conduction bands towards higher energies without losing the visible light absorption properties of the material and introducing impurity states in the gap. The new band edges position with respect to...
