摘要 采用水热法制备了SrTiO3光催化材料,研究了在还原气氛下不同处理时间对SrTiO3光催化分解水制氢性能的影响;此外还研究了单一和复合助催化剂以及担载方法对光解水制氢性能的影响。结果表明:还原气氛中处理1h的样品,其制氢速率比未经处理的样品提高了近40%;担载单一助催化剂比复合助催化剂效果更好;光沉积Pt助催化剂样品具有最高的光催化活性。 Effects of treating time in reduced atmosphere,as well as single cocatalyst and multi-cocatalyst on the photocatalytic activity of SrTiO3 prepared by hydrothermal method for hydrogen generation through water splitting were investigated.Results indicated that the sample treated in reduced atmosphere for 1h showed the 40% enhanced photocatalytic activity for hydrogen evolution in comparison with the untreated sample.SrTiO3 loaded with single cocatalyst by photodeposition exhibited better performance than that of SrTiO3 loaded with multi-cocatlysts.Moreover,the sample loaded with Pt showed the highest activity.
