采用一种简单有效的合成方法制备了聚磷腈包覆碳纳米管复合材料，并将其作为直接甲醇燃料电池催化剂载体。采用混合还原剂制备了聚磷腈包覆碳纳米管负载Pt-Co催化剂。用透射电镜、X射线衍射仪和电感耦合等离子体对PZAF/MWCNTs、PZS/MWCNTs、Pt-Co/PZAF-MWCNTs和Pt-Co/PtZAF-MWCNTs进行了表征。采用循环伏安法研究了Pt-Co/PZAF-MWCNTs、Pt-Co/PtZAF-MWCNTs催化剂对甲醇氧化的电催化活性。Pt-Co/PZAF-MWCNTs复合材料具有分散性好、粒径小、质量活性高的特点。
The composite of polyphosphazene-coated carbon nanotubes is prepared by a simple and efficient synthesis method and regarded as an improved catalyst support for direct methanol fuel cell. Catalyst of Pt–Co supported on polyphosphazene-coated carbon nanotubes is prepared using mixed reducing agents. The PZAF/MWCNTs, PZS/MWCNTs, Pt–Co/PZAF-MWCNTs and Pt–Co/PZS-MWCNTs are measured by transmission electron microscopy, X-ray diffraction and inductively coupled plasma. The electrocatalytic activity of Pt–Co/PZAF-MWCNTs, Pt–Co/PZS-MWCNTs catalysts for methanol oxidation has been investigated by cyclic voltammetry. The composite of Pt–Co/PZAF-MWCNTs shows a good distribution, small particle size and high mass activity.
