摘要

通过优化处理商品五氧化二钽（Ta

），制备得到含有结晶水的Ta

·nH

O无定型化合物，在硫脲和NH

的共同作用下，在较短时间内成功合成出氮氧钽（TaON）纳米光催化剂。测试结果表明，TaON半导体在形貌上表现出大量的蜂窝孔状结构，比表面积相对于传统体相提高了6倍。在光催化性能方面，多孔的TaON半导体材料具有一定的光催化选择性氧化苯甲醇的能力，而在Pd、Ag助催化剂的共同作用下，其性能能够得到进一步的提高。

Abstract

With the co-action of NH

and urea

TaON nano-photocatalyst was successfully synthesized within shorter time using the amorphous Ta

·nH

O compound as precursor

which was prepared by optimized treatment of commercial Ta

. The results indicated that TaON semiconductor present special structure with amounts of pores like honeycomb

and its specific surface area was 6 times higher than that of traditional TaON. For the photocatalytic performance

multihole TaON showed a certain ability of photocatalytic selective oxidation of benzyl alcohol. Such property could be improved with the coaction of Pd and Ag.
