摘要
采用沉淀法制备Fe_2O_3粉体。用XRD、FTIR对样品进行表征,以刚果红为研究对象,紫外光为光源,研究了催化剂前驱体焙烧时间、催化剂前驱体焙烧温度、催化剂用量、刚果红初始浓度、光照时间等对刚果红降解率的影响。结果表明当焙烧时间3 h,焙烧温度400℃,催化剂用量0.3 g,刚果红初始浓度10 mg/时,光催化降解率达到90%以上。
A series of novel α-Fe_2O_3 composite photocatalysts were synthesized by a solution based precipitation method. The resulting products were characterized by powder X-ray diffraction（XRD） and FTIR. The photocatalytic activities of the samples on the degradation of Congo red under ultraviolet was evaluated. The degradation rate of Congo red with 0.3 g α-Fe_2O_3 roasted for 3 h at 400 ℃ is up to 90%.
