| 摘 要： | 以陶粒为载体,采用改进的溶胶-凝胶法制备B、Ni共掺杂陶粒负载纳米TiO2光催化剂。利用XRD,TG-DTA,FT-IR等手段对其组成、结构等进行分析和表征。以250 W紫外灯为光源,三乙胺为目标污染物和电子给体,考察了B-Ni2O3-TiO2/陶粒合成体降解污染物耦合光解水制氢的光催化性能;结果表明：所制得的B-Ni2O3-TiO2/陶粒催化剂具有较高的产氢效率,并探讨了焙烧温度、三乙胺溶液初始浓度等对催化剂光催化活性的影响。

| Abstract: | B-Ni2O3-TiO2/haydite composite photocatalysts were prepared via modified sol-gel method by a carrier of haydite.The as-prepared composites were analysed and characterized with regard to their components,structure etc.by XRD,TG-DTA and FT-IR.Using triethylamine as the pollutants and electron donors,photocatalytic hydrogen generation and decomposition of the pollutants over B-Ni2O3-TiO2/haydite were studied by 250W UV lamp.It is showed that this preparation leads to a highly photocatalytic hydrogen generation activity.Meanwhile the effects of calcination temperature and concentration of the pollutants on photocatalytic hydrogen generation were also investigated. |
