Improvement on Fabrication of Nano-Porous Pseudo-Carbon Paste Electrode (Nano-PPCPE)

摘要

A novel and sensitive nano-porous pseudo-carbon paste electrode (nano-PPCPE) was described. Nano-PPCPE was fabricated by mixing plystyrene (PS) micropheres as the template, graphite powders as the fillers, pyrrole as the precursor of polymer which actually acted as the paste. Experimental results showed that when the ratio of applied PS micropheres/graphite powder was 2:1, and the PS micropheres possessed a smaller particle size, the obtained nano-PPCPEs displayed a larger specific surface area which was even up to 332.09 m2/g. In comparison with the traditional carbon paste electrode, the nano-PPCPE has good electrochemical behavior, such as strong current intensity, good stability, demonstrating important significance in electrochemical detection and analysis.
