Preparation and Electrocatalytic Performances of Carbon Nanotubes Supported Poly-Cobalt-Phthalocyanine

采用原位合成方法制备了聚合酞菁钴/多壁碳纳米管(Poly-CoPc/MWCNT)复合材料。运用紫外–可见吸收光谱(UV-Vis)和透射电镜方法(TEM)对复合材料的结构进行了表征，结果显示生成的聚合酞菁钴通过π-π作用包裹在碳纳米管的表面并且聚合酞菁钴的厚度及均匀度随着反应时间和反应温度的改变而发生了变化；采用循环伏安(CV)电化学方法研究了反应时间和反应温度与复合材料的氧还原催化性能之间的关系，研究发现，反应时间和反应温度对复合材料的氧还原催化性能产生了很大的影响。 We prepared Cobalt-phthalocyanine polymers/MWCNT (Poly-CoPc/MWCNT) with in-situ synthesis method. The products were characterized by UV-Vis and TEM, the results showed that Poly-CoPc has been adsorbed onto the surface of MWCNT through π-π interactions and with the change of the reaction time and reaction temperature, the thickness and uniformity of Poly-CoPc are changed. The correlation between the electrocatalytic activity of the modified electrodes of obtained Poly-CoPc/MWCNT and reaction time and reaction temperature were measured by cyclic voltammetry (CV). The results showed that reaction time and reaction temperature have great influences on its oxygen reduction performances.
