The cobalt hexacyanoferrate nanocrystals (Nano-CoHCF) with uniform shape and size were electrochemical deposited on the electrode surface modified with the overoxidized polypyrrole (OPyox) film in the presence of ethylene diamine tetraacetic acid (EDTA). The conceivable effect of EDTA and OPyox film was studied using SEM and electrochemical techniques. The experiment results showed that the nucleation...
Carbon nanofibers (CNFs) are grown on metal catalysts and electrochemical treatment is used to remove the metal catalyst residuals from the as-grown CNFs. For comparison, the CNFs are also purified by a chemical method and a thermal method. The oxygen reduction reaction (ORR) properties of CNFs purified by these three methods are examined by cyclic voltammetry. CNFs treated by the electrochemical...
