配合法制备InNbO_4及其光催化活性的研究

以配合法制备InNbO4催化剂,研究了在甲醇为电子给体,Pt为助催化剂的条件下,InNbO4光催化分解水的产氢活性。并与固相合成法制备的InNbO4光催化活性进行对比。通过X-射线衍射和比表面分析对两种方法制备的催化剂进行表征。研究发现,在焙烧温度为900℃、时间为12 h时,配合法制备的InNbO4光催化产氢活性最高(87.27μmol),为固相合成法的2倍。

Preparation of InNbO4 by complex method and its photo catalytic activity

The InNbO4 photocatalyst was prepared by complex method;the photocatalytic activity for hydrogen evolution was studied with methanol as electron donor and Pt as promoter catalyst.Comparison of the photocatalytic activity of InNbO4 prepared by the polymerized complex and solid-state reaction method was made.The catalysts prepared by different methods were also characterized by XRD and BET studies.The maximum photocatalytic activity was obtained for Pt(0.10%)/ InNbO4 prepared by the PC method at 900 ℃ for 12 h;the hydrogen generation amounting to 87.27 μmol,two times larger than that for a sample prepared by the conventional solid-state reaction method.
