One-Dimensional Porous Carbon/Platinum Composites for Nanoscale Electrodes

摘要

Nanostructured carbon materials, especially one-dimensional (1D) carbon nanotubes (CNTs), are of great interest for the development of nanoelectronics, catalytic reactors, and gas sensors. Recently, work has focused on the dispersion of metal (usually platinum) nanoparticles in CNTs for applications as electrodes for fuel cells. It is known that the efficiency of the catalyst is low in the case of the ink process for assembling membrane electrodes because of the difficulty of accessing inner electrocatalytic sites.
