Electrocatalytic activity of Pt/MoSe_2 electrodes prepared by an intercalation-exfoliation method:Application on the oxidation of methanol

摘要

The catalytic oxidation of methanol is of great importance because of its application in direct methanol fuel cell systems.The oxidation process can produce carbon dioxide ,as well as carbon monoxide.The carbon monoxide molecule can poison the platinum electrode,leading to the deactivation of the anode catalysts in direct methanol fuel cell systems.Several efforts have been made to improve the catalytic activity of the electrodes used in fuel cell.
