As long as the semiconductor absorption of light energy is less than the band gap£¬can be stimulated to produce electrons and holes£¬ which may be used for semiconductor photocatalyst. »òÕߣº So long as the semiconductor absorbs the energy of light is smallerthan its energy gap, can sufficiently receive stirs up produces theelectron and the hole, this semiconductor on possibly serves as thephotocatalyst . »òÕߣº As long as the optical energy that semiconductor absorbs is smaller than whose forbidden band width, can be enough to accept the exciting creation electron and hole , be semiconductor's turn to may be used as photocatalyst right away. |
