Abstract

The gas flow dependence on hollow carbon nano-cages (HCNCs) as catalyst support was investigated. HCNCs with varying flows (40, 120, and 200 l/h respectively) were continually synthesized. The increased gas flow introduced a relatively high specific surface area (SSA) and a good graphitic structure. After being loaded with a high ratio of 50 wt% platinum, the as-obtained Pt/HCNCs displayed improving electrochemical activity in both hydrogen adsorption/desorption and methanol oxidation with increasing flow. The present analysis provides some understanding of the effects of the gas flow in Pt/HCNCs in fuel cell applications.
