| Abstract: | This paper introduced the basic principle of photocatalytic oxidation and the existing problems. Discussed how to im- prove the photocatalytic activity as well as the main way to research status. Improving the photocatalytic oxidation activity in two major ways：Suppress the electron-hole pairs composite as well as broaden the spectral response range of photocatalytic composite. By means of further simplification：effective use of solar energy. Photocatalytic in solving wastewater treatment has broad prospects for development. |
