中文摘要: 采用十二烷基硫酸钠(SDS)为改性剂制备了表面具有有机基团的CuO/TiO2催化剂。采用XRD、低温氮吸附-脱附、BET、XRF、FTIR 、UV-Vis和三维荧光等手段对催化剂的晶型、结构、化学组成、表面基团和光致发光性能进行了表征。结果发现SDS浓度不对催化剂的紫外可见吸收阈产生明显影响,吸收阈均在830nm以上。但SDS加入后催化剂的液氮吸附曲线由Ⅳ型等温曲线变为Ⅴ型。当浓度为临界胶束浓度时催化剂晶粒和平均孔径最大;比表面积和总孔容最小;催化剂中氧空位数量和表面C—C和—CH—基团最多,催化剂的光催化性能最好。

N2 adsorption-desorption
BET、XRF、FTIR 、UV-Vis DRS and three-dimensional fluorescence. The results show that UV-Vis absorption edges have nothing to do with the concentrations of SDS
and the UV-Vis absorption edges reach 830nm. But the N2 adsorption isothermal curves change from Ⅳ type toⅤ after SDS is added. Although the BET surface and total pore volume become the smallest when the concentration of SDS is critical micelle concentration(CMC)
the particle size and average pore diameter reach the biggest. The oxygen vacancy concentration and groups of C—C and —CH— also reach the most at CMC. Photocatalysts prepared under this concentration has best catalytic performance.
