摘要
针对碳纳米管作催化剂载体材料的特性,采用灼烧灰化预处理,间接碘量法测定了Co3O4/CNTs载钴量,获得稳定而准确的分析结果。结果表明,制备Co3O4/CNTs催化剂时所加入的钴并不全部吸附在碳纳米管上;载钴效率随着碳纳米管载钴量的增加而降低。
The sample was pretreated by calcination and the ashed residue was dissolved with HC1 and HNO3. An iodimetric titration was used for the determination of colalt in Co3O4 loaded carbon nanotube catalyst.Results showed that the cobalt amount added in catalyst preparation was not completely absorbed in carbon nanotube, and the loading efficient was decreased with the increase of loading amount in the catalyst.
