光促CO2和H2O在Cu/TiO2-NiO上的表面反应
摘要:
采用溶胶凝胶法制备了n-p复合半导体材料Cu/TiO2-NiO,并用TG-DTA和TPR方法进行了前驱体的表征;利用XRD,TEM,UV-Vis技术测试了材料的晶态结构和吸光性能;CO2和H2O的光促表面催化反应(PSSR)实验结果表明,所制备的Cu/TiO2-NiO能够明显促进二者的反应,室温条件下有CH3OH、CH4和CO生成,其中对CH3OH的选择性较高,材料组分配比对PSSR有显著影响,在质量分数为0.50% Cu/TiO2-2.0% NiO上获得了最高CO2转化率。

Photo Stimulated Surface Reaction of Carbon Dioxide and Water on Cu/TiO2-NiO
Abstract:
The n-p coupled semiconductor materials Cu/TiO2-NiO were prepared by a sol-gel method, TG-DTA, TPR, as well as XRD, TEM and UV-Vis were used to characterize the crystal structure and photo absorbing ability of the precurors and final catalysts, respectively. The Photo Stimulated Surface Reaction(PSSR) of CO2 and H2O on Cu/TiO2-NiO has been investigated. The results revealed that CH3OH, CH4 and CO can be produced by PSSR at normal temperature with high selectivity of CH3OH. The composition of the material shows significant effects on the PSSR. The highest CO2 conversion was obtained on 0.50% Cu/TiO2-2.0% NiO catalyst.
