以钛酸四丁酯为原料,Al2O3为载体,用溶胶-凝胶法制备负载型TiO2,在UV-TiO2体系中对吡啶(PD)进行光催化降解,并研究了将TiO2负载在不同铝源所制备的Al2O3后光催化剂的差异,结果表明:负载型TiO2光催化剂加入量为10mg/40mL,吡啶的光催化降解反应符合一级动力学方程;吡啶中氮转化成氨氮.将TiO2负载在Al2O3上后利用率提高了6倍左右.
TiO2 was prepared by sol-gel method using tetrabutyl titanate as raw material and Al2O3 as carrier. Photocatalytic degradation of pyridine (PD) was carried out in UV-TiO2 system. The effects of loading TiO2 on different aluminum sources The results showed that the photocatalytic degradation of pyridine was in accordance with the first-order kinetic equation and the nitrogen in pyridine was converted into ammonia nitrogen.The photocatalyst TiO2 was supported on Al2O3 After the utilization rate increased about 6 times.
