摘要

In this study, an efficient and viable microwave-assisted polyol route was adopted to decorate Pt nanoparticles on multi-walled carbon nanotubes (CNT). Carbon corrosion tests were conducted on bare CNT (T), functionalized CNT (f-T), and commercial carbon (Vulcan XC-72R); our results indicate that f-T have the highest resistance toward corrosion, indicating its high stability in corrosive environments. The cyclic voltammetry curves were obtained before and after 5000 cycles by subjecting the electrocatalyst to harsh potential cycling; our test results imply that Pt/CNT are more durable when compared to commercial Pt/C. Then, fuel cell studies comprising Pt/CNT as cathode electrocatalyst was studied, and the results showed enhanced performance (maximum power density: 384 mW cm−2) for Pt/f-T than commercial Pt/C (367 mW cm−2) in Polymer electrolyte membrane (PEM) fuel cell, indicating the potential use of carbon nanotubes as support in PEM fuel cell.
