摘要
CO 有毒气体的排放严重危害环境安全和人类健康。目前，利用催化剂催化氧化 CO 已成为主流研究方向。本研究采用溶剂水热法制备了不同配比的 CuO@TiO2 催化剂，考察了反应预处理温度等因素对 CO 催化氧化性能的影响。实验结果表明，该催化剂在 350℃ 预处理 2 h 的条件下，115℃ 时 CO 的转化率可达 100%。这种优异的性能得益于活性组分在 TiO2 载体表面的均匀分布，以及溶剂水热法构建的大孔隙结构增强了对 CO 的吸附和活化。这项工作为制备 CO 氧化催化剂提供了一种思路。
Catalytic oxidation of CO over CuO@TiO2 catalyst: The relationship between activity and adsorption performance
The emission of CO toxic gases seriously endangers environmental safety and human health. At present, the use of catalysts for catalytic oxidation of CO has become the mainstream research direction. In this study, CuO@TiO2 catalysts with different ratios were prepared by solvent hydrothermal method, and the effects of reaction pretreatment temperature and other factors on the catalytic oxidation performance of CO were investigated. The experimental results show that the catalyst can achieve 100% conversion of CO at 115°C under the condition of pretreament at 350°C for 2 h. This excellent performance is due to the uniform distribution of the active component on the surface of the TiO2 support, and the large pore structure constructed by the solvent hydrothermal method enhances the adsorption and activation of CO. This work provides an idea for the preparation of CO oxidation catalysts.
