Research on Photoelectric Properties of ZnO-based Semiconductor Material

Abstract In recent years, many semiconductor materials have been applied to the photocatalysis technology. As a with wide band gap (3.37 eV), ZnO has received extensive attention in photocatalytic degradation of organic pollutants due its rich morphology, low cost and other advantages. However, ZnO, it can only absorb ultraviolet light (accounting for about 4% whole solar spectrum), which greatly limited application materials. BiOI/ZnO binary complexes were synthesized by simple hydrothermal solvothermal methods. Their phenol activities tested under different sources. The mechanism was reasonably explained free radical trapping experiment, surface photovoltage, transient fluorescence tests.
