反蛋白石结构光催化剂的制备与应用进展

光子晶体是一种具有光子禁带的周期性结构,在一定的波长范围内,光在晶体的某些方向上是不允许传播的;反蛋白石结构作为一种典型的光子晶体结构,具有慢光效应、多次散射效应和放大光子吸收、发射等特性,可以提高催化剂的传质效率、活性中心的曝光率和其集光性能,因此其在光催化领域受到越来越多的关注.我们综述了反蛋白石结构的光学性质;将反蛋白石结构光催化剂的制备方法归结为三步法和两步法两大类,列举了所包含的具体方法,总结了各自的优缺点;同时阐述了反蛋白石结构光催化剂的应用领域,最后对其在光催化领域的研究和发展趋势做出了展望.

Preparation and Application of Inverse Opal Photocatalyst

The photonic crystal is a periodic structure with a photonic band gap, certain wavelength range of light isnot allowed to propagate in certain directions of the crystal. As a typical photonic crystal, inverse opals have slow light effects, multiple scattering effects, amplified photon absorption and emission characteristics, can improve the mass transfer efficiency of the catalyst, the exposure rate of the active center and its light collection performance, therefore, more and more attention has been paid in the field of photocatalysis. In this review, the optical properties of inverse opal structure are introduced, summarizing the preparation methods of the inverse opal structure photocatalyst into two categories: the three-step method and the two-step method, listing the respective advantages and disadvantages of specific methods, meanwhile, expounding the application field of inverse opal structure photocatalyst. Finally, the future of inverse opal structure photocatalyst in the field of photocatalysis are forecasted.
