摘　　要：以钛酸四丁酯、乙醇、乙酸、硝酸锌为主要原料,采用溶胶-凝胶法制备Zn掺杂TiO_2光催化剂,催化降解苯酚。主要研究了锌钛摩尔比、醇钛体积比、焙烧温度、焙烧时间等条件对Zn掺杂TiO_2光催化剂降解苯酚的影响。实验证明,当锌钛摩尔比为0.010、醇钛体积比为8、焙烧温度为500℃、焙烧时间为1.5h时,催化效果最好。The sol-gel method is used to prepare Zinc doping TiO2 light catalyst with main materials of tetra-n-butyl titanate,ethanol,acetic acid,zinc nitrate,then degrades phenol.Main influencing factors of molar ratio of zinc to titanium,olume ratio of alcohol to titanium,roasting temperature,roasting time are researched.The results of experiment show：when the molar ratio of zinc to titaniumn（Zn∶Ti）is 0.010,olume ratio of alcohol to titanium V（C2H5OH∶Ti）is 8,roasting temperature is 500 ℃,roasting time is 2.5 h,the catalytic effect is the best.
