摘　　要：椰壳活性炭凭其较大的比表面积和较好的活化性能,已逐渐成为降解挥发性有机污染物的主要催化剂载体。研究采用浸渍法制备了以多孔椰壳活性炭颗粒作为载体的金属氧化物催化剂,负载了Mn、Co、Fe不同金属元素的单一氧化物和复合金属氧化物,通过XRD、SEM、EDS等研究手段对不同组分的催化剂进行了表征分析。结果表明:通过改变掺杂金属比和焙烧温度可以制得活性不同的催化剂;当金属负载比为Mn∶Co∶Fe=3∶2∶1、焙烧温度为550℃时,催化剂表现出最佳的催化性能。本研究不仅有助于实现固体废物椰壳的资源化利用,达到经济环保的目的,也能为实际环保工作提供技术支持和理论依据。Coconut shell active carbon has gradually become the major catalyst carrier for the degradation of volatile organic compounds due to its large specific surface area and good activation performance.The impregnation method was used to prepare the metal oxide catalysts with porous coconut shell active carbon particles as carriers in this study.It was loaded with single metal oxide and composite metal oxide catalysts with metal elements of Mn,Co and Fe.The catalysts with different compositions were characterized and analyzed by XRD,SEM and EDS.The results showed that catalysts with different activities could be prepared by changing the doping metal ratio and calcination temperature.When the loading ratio of metal components was Mn∶Co∶Fe=3∶2∶1,and the calcination temperature was 550℃,the catalyst showed that the optimal catalytic performance.The research could not only help to realize the resource utilization of solid waste coconut shells,achieve the purpose of economic and environmental protection,but also provide technical support and theoretical basis for practical environmental protection work.
