Pore structure dependent activity and durability of mesoporous rhodium nanoparticles towards the methanol oxidation reaction.

This work reports a significant effect of porous structures on the electrocatalytic methanol oxidation performances of Rh-based catalysts. It is demonstrated that a three-dimensional net-like mesoporous structure with ultrathin subunits is beneficial to exposing more active sites and boosting electron transfer inside particles, thus presenting the highest activity.
