摘　　要：针对聚合物不耐高温的问题,本文设计了一种简单实用的方法,将已制备好的Ti O2/MCM-41粉体,通过喷雾沉积的方法固定在PMMA表面。避免了高温焙烧对PMMA造成的破坏。该方法很好的保持了光催化剂的晶型和粒度,催化剂与载体表面结合牢固,为光催化降解水中污染物提供了一个新的思路。A simple and practical method is designed for polymer which can not resist high temperature in this paper. TheTiO2 / MCM-41 powder is loaded on the PMMA surface by the spray deposition method to avoid damage of PMMA in high tem-perature. This method can keep the good crystal form and particle size of photocatalyst and the catalyst combines strongly withthe PMMA matrix, to provide a new way for photocatalytic degradation of organic pollutant in the water.
