Highly dispersed Ru clusters toward an efficient and durable hydrogen oxidation reaction†
Abstract
Here, Ru clusters supported on nitrogen-doped hollow carbon spheres show a remarkable activity and durability toward the hydrogen oxidation reaction (HOR) and H2–O2 fuel cell performance in alkaline media. Theoretical simulations indicate that Ru clusters endow a thermodynamically favourable HOR kinetics and an optimal hydrogen adsorption affinity.
