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 1g in 100mL titanic gel shown the best result.After simulated visible light-degradation for 2h,the methyl organge was degraded by 95.7%.
