以酵母细胞为模板,通过生物模板法制得钼酸铁空心微球材料,采用XRD、SEM、FTIR以及氮气吸脱附等手段,对样品的物相、微观形貌及比表面积等进行表征;并以亚甲基蓝模拟染料废水为研究对象,评价了样品的高级氧化催化性能.结果表明:生物模板法得到的钼酸铁空心微球为单斜晶系Fe2 (MoO4)3,样品分散度良好,形貌一致,较好地保持了酵母细胞椭圆形的形貌,平均尺寸约为5.6μm×3.7μm,比表面积为14.9 m2/g;钼酸铁空心微球作为类Fenton催化剂应用于亚甲基蓝模拟染料废水处理,表现出优异的高级氧化催化活性,当催化剂用量为1 g/L、H2O2浓度为300 mmol/L、反应温度25℃、pH=5时,反应60 min后对100 mg/L模拟染料废水中亚甲基蓝的去除率可达98％以上.
