| 摘 要： | 采用有机物前驱法制备了3种尖晶石型铝酸盐催化剂(CoAl_2O_4,ZnAl_2O_4,CoAl_2O_4)。采用FTIR,XRD,UV-Vis DRS等技术对催化剂进行表征,并将催化剂应用于CO_2的光催化还原。表征结果显示:除CoAl_2O_4外,CoAl_2O_4和ZnAl_2O_4在煅烧时均直接形成尖晶石相;CoAl_2O_4,CoAl_2O_4,ZnAl_2O_4的平均粒径分别为25.21,21.35,23.26 nm,禁带宽度分别为1.77,1.45,3.82 eV。分别以煅烧温度为900℃、煅烧时间为4 h时制得的ZnAl_2O_4,CoAl_2O_4,CoAl_2O_4为催化剂,在催化剂加入量为1.5 g/L、CO_2流量为200 mL/min、反应温度为60℃的条件下光催化反应8 h,甲酸产生量分别为443.54,365.65,241.39μmol/g。

| Abstract: | Three kinds of spinel aluminate type catalyst,CoAl2O4,ZnAl2O4,CuAl2O4,were prepared by organic precursor method and characterized by FTIR,XRD,DRS Uv-Vis,and the catalyst was used in photocatalytic reduction of CO2. The characterization results show that：Except for CuAl2O4,CoAl2O4 and ZnAl2O4 directly become spinel phase;The average particle diameters of CoAl2O4,CuAl2O4,ZnAl2O4 are 25.21,21.35,23.26 nm,and the band gap width of them are 1.77,1.45,3.82 eV,respectively. When ZnAl2O4,CoAl2O4,CuAl2O4 prepared by calcination at 900 ℃ for 4 h are used as catalyst respectively,and under the conditions of catalyst dosage 1.5 g/L,CO2 flow 200 mL/min,reaction temperature 60 ℃ and reaction time 8 h,the production quantity of formic acid are 443.54,365.65,241.39 μmol/g,respectively. |
