摘要
以纳米碳酸钙微球为模板,吡咯为前驱体,石墨粉为填料直接诱导合成,廉价简便地制备出一种高灵敏的纳米多孔类碳糊电极,讨论了石墨粉与纳米碳酸钙微球质量比对电极性能的影响。结果表明,选用粒径最小的60-80 nm碳酸钙为模板,当纳米碳酸钙微球与石墨粉的质量比为1:1.5时,纳米多孔碳糊类电极的比表面积可高达923.5 m2/g。以循环伏安法(CV)和交流阻抗(EIS)研究其电化学行为,结果表明,纳米多孔类碳糊电极较纯碳糊电极电性能好,灵敏度高,稳定性和重现性好。
With calcium carbonate microspheres as template, pyrrole as precursor and graphite powder as padding prepared a ultrasensitive nano-porous pseudo carbon paste electrode (nano-PPCPE). Investigated the impacts of mass ratio of calcium carbonate microspheres and graphite powder on the electrode behavior. The results showed that with the calcium carbonate microspheres of size 60-80 nm as template, nano-PPCPEs surface area were up to 923.5 m2/g when the mass ratio of calcium carbonate microspheres/graphite powder was 1:1.5. Studied the nano-PPCPEs electrochemical behavior by the methods of cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS), the results showed that the prepared electrode had good electrochemical behavior, high sensitivity, stability and reproducibility
