| Abstract: | Nafion (Nf)-thionine (Th) ion-pair as dispersant and second catalyst has been introduced in Pt catalyst for methanol electrooxidation and the resulting catalyst supported on carbon (NfThPt/C) has been investigated by electrochemical method. For the same loading mass of Pt, the peak current density of methanol oxidation on the NfThPt/C/graphite electrode is about 7.25 and 3.04 times as high as that on the E-TEK Pt/C/graphite and E-TEK PtRu/C/graphite electrodes, respectively. Moreover, NfThPt/C catalyst shows excellent anti-poisoning ability and long-term cycle stability. The electrocatalytic properties of Pt for methanol electrooxidation are improved by Nf-Th ion-pair. |
