摘要: 以生物质材料羊毛毡为前驱体，通过热解的方法一步制备了杂原子(N，O、S和P)掺杂碳材料，并用SEM、EDS和FTIR对其进行表征。同时，用该材料作为电Fenton阴极催化降解罗丹明B废水，并对影响电Fenton过程的重要因素如：溶液的初始pH值和Fe2+的浓度进行了优化。实验结果表明，该材料有很高的催化活性，在溶液的初始pH为3，Fe2+的浓度为0.5 mmol∙L−1时，用该催化剂作为电Fenton阴极降解50 mg∙L−1的罗丹明B溶液，降解时间为120分钟，罗丹明B的去除率可达到99.5%。由于该催化剂制备方法简单，成本低，催化活性高，稳定性好，在处理有机废水方面有很好的应用前景。
Abstract: The heteroatoms (N, O, S and P) doped carbon material were prepared by a facile strategy through pyrolytic treatment of wool felt, and their properties were characterized by SEM, EDS and FTIR. Meanwhile, the material was used as electro-Fenton cathode for rhodamine B degradation. The effect of significant parameters including the initial pH and Fe2+ dosage on the removal efficiency was investigated for electro-Fenton process. It was indicated that initial Fe2+ concentration of 0.5 mmol∙L−1 at pH 3 were the optimum conditions for the removal of 50 mg∙L−1 RhB solution. The degradation time was 120 min, and the removal rate of rhodamine B was 99.5%. Because the catalyst has the advantages of simple preparation method, low cost, high catalytic activity and good stability, the catalyst has a good application prospect in the treatment of organic waste water.
