The performance of Pt catalyst supported on carbon nanowall (CNW) and vertically aligned carbon nanofiber (VACNF) for methanol electro-oxidation has been compared. Pt/CNW and Pt/VACNF electrodes were fabricated by growing CNW and VACNF on carbon papers with inductively coupled plasma enhanced chemic...
