In order to enhance the performance of fuel cell electrode, carbon nanotubes (CNTs) were directly grown on carbon paper and Pt nano particles were dispersed on CNTs by chemical vapor deposition (CVD) or electrochemical deposition (ECD) method. CVD and ECD have recently been adopted as catalyst preparation methods due to their advantages such as high purity of deposits, simple process, easy control of loading mass, and small particle size. The catalytic activity of Pt/CNTs was measured by CO chemisorption results and by comparing their mass activity. SEM and TEM results show that Pt particles are highly dispersed on CNTs surface. |
