High-efficiency Pt catalyst immobilized on hierarchical N-doped carbon nanocages for preferential oxidation of CO in H2†
Abstract
The N-doped carbon nanocage-supported Pt nanoparticle catalyst exhibits high activity and stability for preferential oxidation of CO in H2 over a wide temperature range of 80–180 °C, which is attributed to the modulated electronic structure of Pt and high accessibility of active sites endowed by hierarchical N-doped carbon nanocages.
