摘要 采用微波辐射加热方法制备出负载型TiO2/NaY光催化剂,采用X-射线粉末衍射(XRD)、红外光谱(IR)与紫外可见漫反射谱(UV-vis DRS)对催化剂结构进行了表征,以苯酚光催化降解与矿化对催化剂活性进行评价.结果表明,微波辐射加热方法促进了表面TiOx物种与载体NaY间的相互作用,TiO2在载体表面难以形成晶相结构,同时也导致了NaY分子筛结构的坍塌,因而催化剂对水体中苯酚的光催化降解与矿化活性较低. The TiO2/NaY film Structure and catalytic properties of photo-catalysts photo-catalysts were prepared by were studied by microwave irradiation heating method. using XRD, FT-IR, UV-Vis DRS and reaction test of photo-catalytic degradation of phenol. It is shown that there is low photo-catalytic activity for degradation of phenol in water, and little crystal TiO2formed on NaY support surface. They may result from strong interaction between TiOxspecies with NaY support, and collapse of the support structure by microwave method.
