Metal-organic framework templated Pd/CeO₂@N-doped carbon for low-temperature CO oxidation.

ABSTRACT: A new Pd/Ce based metal-organic framework is designed and synthesized as a self-sacrificial template for fabrication of an efficient catalyst for CO oxidation. The catalyst obtained by thermal annealing at 700 °C (Pd/CeO₂@NC-700) is composed of N-doped carbon with embedded Pd and CeO₂ nanoparticles, which are highly dispersed and closely connected in the N-doped carbon; the high Pd loading (33.7 wt%) and the coupling between Pd and the CeO₂ phase synergistically boost the CO oxidation performance. The Pd/CeO₂@NC-700 catalyst exhibits a 100% conversion temperature of 89 °C and excellent long-term stability. By combining structural characterization with density functional theory calculations, two possible CO oxidation pathways of TPB and TOP are re
