中文摘要:
      本文采用阳极氧化方法成功制备出整体多孔道Fe-Fe2O3,并以整体多孔道Fe-Fe2O3为阴极,铂片为阳极,外加H2O2,构建非均相芬顿体系,利用电催化作用促进Fe(Ⅲ)还原为Fe(Ⅱ)。结果显示在溶液pH值为7,H2O2浓度为1.0 mmol/L,施加电压为-0.4 V的条件下,苯酚去除率在60 min内能够达到达到96%,这表明整体多孔道Fe-Fe2O3是较理想的非均相催化剂。ICP溶出测试结果说明,电催化作用能够有效促进Fe(Ⅲ)还原为Fe(Ⅱ),从而提高催化效率。
英文摘要:
      The Fe-Fe2O3 monolith was successfully prepared by anodization method in this paper, Fe-Fe2O3 monolith and Pt sheet were employed as the cathode and anode, respectively, and H2O2 was added externally during the heterogeneous Fenton system. Meanwhile, the Fe (III) was reduced to Fe (II) by electrocatalysis. It was found that the phenol removal rate can reach 96% in 60 min under the condition in which pH was 7, H2O2 concentration was 1.0 mmol/L and applied voltage was -0.4 V. The result showed that Fe-Fe2O3 monolith was an ideal heterogeneous catalyst. The results of ICP test showed that electrocatalysis can effectively promote the reduction of Fe (III) to Fe (II), thereby improve catalytic efficiency.
