【摘要】 TiO2是一种优良的光催化材料,在TiO2表面负载金属银能显著提高其光催化活性,目前在TiO2表面沉积银的方法主要有溶胶-凝胶法、光化学沉积法、Ag2CO3法、银镜反应法、光催化还原金属离子法等。在对掺银改善纳米二氧化钛光催化性能的研究基础上,人们发现了卤化银作为光催化剂的光催性能。通过比较发现,AgCl在光催化降解水中有机污染物的过程中应该有与TiO2相似的反应机理。更多还原

【Abstract】 TiO2 is a good photo-catalytic material.Loading Ag on the surface of TiO2 will improve its photo-catalytic properties dramatically.The main methods of loading Ag on the surface of TiO2 include the photo-deposition method,the sol-gel technique,the Ag2CO3 method,the silver mirror reaction,the photo-catalytic reduction of metal ions,etc.The photo-character of AgX catalyst is found on the study of Ag/TiO2.It is found that the mechanism of using AgCl as the photo-catalyst to degrade the organic contamination in water is similar to that of TiO2.更多还原
