Fine Size Control of Platinum on Carbon Nanotubes: From Single Atoms to Clusters

摘要

Electrocatalyst design is a key factor for enhancing the performance of a fuel cell. Since dispersity and cluster size mainly affect the properties of the electrocatalyst, it is necessary to devise a proper synthetic route to highly dispersed and size-controlled clusters.[1], [2] Many studies on dispersion and size control of Pt clusters on carbon supports for electrocatalysts have been conducted to investigate the effect of size on electrocatalytic activity from a fundamental scientific viewpoint and to enhance the performance of fuel cells with low noble-metal loadings in engineering applications.[3]-[11]
