摘要

以甘蔗渣为模板,采用浸渍-热转换法成功制备了具有双钙钛矿结构的稀土掺杂La_2FeNiO_6光催化剂,通过XRD、SEM、TG-DSC、UV-Vis对样品的物相组成、形貌和光催化性能进行了表征,结果表明:所得La_2FeNiO_6具有多孔片状结构,最佳煅烧温度为600℃,Er的最佳掺杂量为x=0.05 mol,光照30 min对亚甲基蓝溶液的降解率为78.94%。
        Rare earth doped photocatalyst La_2FeNiO_6 with double perovskite structure is prepared by impregnation-thermal conversion method with bagasse as template. The obtained samples are characterized by XRD, SEM, TG-DSC and UV-Vis to reveal phase composition, morphology and photocatalytic properties. The results show that the prepared photocatalyst La_2FeNiO_6 has a porous chip structure, the best calcination temperature is 600℃, the optimum amount of Er doping is x=0.05 mol, and the degradation rate of methylene blue solution under the sun light for 30 min is 78.94%.
