Abstract:
？以cu(no3)2·3h2o和p25为前躯体,通过简单浸渍法制备了cuo/tio2光催化剂,利用n2物理吸附、xrd、tem、uv-vis漫反射光谱分析了催化剂的结构特性。研究了cu组分的负载量、催化剂在反应液中的分散量、催化剂焙烧温度、反应液中甲醇浓度对cuo/tio2光催化反应产氢活性的影响,并考察了催化剂的稳定性,提出了该体系光催化反应的机理。结果表明,cu的适宜负载量为2.0%~7.5%(质量分数),在cu质量分数2.0%、催化剂焙烧温度350℃、甲醇的体积浓度为10%、催化剂分散量为1.0g/l时,产氢活性可达到1022μmol/(h·g),并且该催化剂具有较好的稳定性。
