上转换材料复合介孔tio2晶须的可见光催化性能
DOI: doi:10.3969/j.issn.1671-7627.2012.02.009, PP. 39-43
Keywords: 介孔tio2晶须,y3al5o12:er,上转换材料,可见光催化
Abstract:
用溶胶凝胶法制备上转换发光材料y3al5o12:er。反射光谱、发射光谱表明：y3al5o12:er在480nm光的激发下，产生2个<387nm的紫外光发射峰。将上转换材料介孔tio2晶须复合成可见光催化剂，采用x线衍射仪(xrd)、场发射扫描电子显微镜(fesem)以及低温n2吸附脱附(bet)等对催化剂进行表征，通过光催化降解亚甲基蓝(mb)，对催化剂的活性进行测试。结果表明:复合上转换材料的介孔tio2晶须在可见光下能够有效降解mb，10%y3al5o12:er的介孔tio2晶须的mb降解率为73%。
