| Abstract: | Because TiO2 only can absorb ultraviolet light with wavelength shorter than 387 nm,its practical application is limited.In recent years,a novel material photonic crystal has become the research hotspots in enhancing the optical absorption rate.The development in photonic crystals in enhancing the light absorptivity of TiO2 was reviewed,especially its application in solar cells,organics photocatalysis degradation and photocatalytic water splitting to hydrogen.The research on improving the optical absorption rate of photonic crystals was introduced.The research results showed that photonic crystals had remarkable effects on the enhancement of the optical absorption rate of TiO2.It has important significance to understand the research progress in application and the law status of photonic crystals for the high efficient photocatalyst preparation. |
