摘要

Abstract

Three nanocomposites of phosphomolybdic acid supported on TiO2and ZnO nanoparticles were synthesized and characterized by means of FESEM, FTIR and XRD analysis. Photocatalytic activity of the synthesized nanocomposite was investigated for aniline as an organic pollutant model. Relatively, good degradation efficiency above 70% was achieved for all nanocomposites in presence of hydrogen peroxide as electron scavenger. The kinetic study showed that photocatalytic degradation of aniline followed the Langmuir-Hinshelwood model. Results showed that hydroxyl radicals and holes play an important role in photocatalytic degradation of aniline using synthesized nanocomposites. These results suggested that synthesized nanocomposites could be promising photocatalysts in the removal of aniline from aqueous solutions.

Highlights

抽象

TiO 2 和ZnO纳米粒子的特征。研究了合成纳米复合物的光催化活性，以苯胺作为有机污染物模型。在作为电子清除剂的过氧化氢存在下，所有纳米复合材料都达到了70％以上的良好降解效率。动力学研究表明，苯胺的光催化降解跟随Langmuir-Hinshelwood模型。结果表明，羟基自由基和孔在使用合成纳米复合材料的光催化降解苯胺的光催化降解中起重要作用。这些结果表明，合成的纳米复合材料可以是在从水溶液中除去苯胺的光催化剂。
