摘　　要：以花生壳和钛胶为原料,利用溶胶-凝胶法合成了花生壳改性TiO2晶体。以甲基橙为降解对象,研究花生壳改性TiO2的光催化性能,探讨了掺杂量、煅烧温度对光催化剂活性的影响。结果表明:采用溶胶-凝胶法制备的花生壳改性TiO2对甲基橙具有一定的光催化活性,能够将其降解;在100℃下煅烧,100mL钛胶掺杂1g花生壳所制得的催化剂对甲基橙的降解效果最佳,可见光光照2h,甲基橙降解率达到95.7%。Peanut shells and titanic gel was used as raw materials to prepare peanut shells modified TiO2 crystal by sol-gel method.The visible light-degradation performance of methyl organge was studied to discuss the peanut shells’doping amount,calcination temperature whether exercised an influence on it.The results suggested that peanut shells modified TiO2 prepared via sol-gel method shown the photocatalytic activity for the decomposition of methyl orange:with the condition of being calcined at 100℃,peanut shells doping amount of 1 g in 100 mL titanic gel shown the best result.After simulated visible light-degradation for 2 h,the methyl organge was degraded by 95.7%.
