摘要

Abstract

hydrogenation to value-added chemicals is a promising pathway to solve CO

-relevant environmental problems but still remains a great challenge. Herein

we report a CeO

nanostructure supported Rh single atoms (Rh-SAs/CeO

) catalyst and was used for the efficient CO

hydrogenation to HCOOH. The Rh-SAs/CeO

exhibited high catalytic activity with turnover numbers (TON) up to 221 at 200 ℃

which was 4-fold to that of CeO

supported Rh nanoparticles (Rh-NPs/CeO

). Moreover

HCOOH selectivity for Rh-SAs/CeO

reached 85%

much higher than that of Rh-NPs/CeO

(46%). Mechanism studies revealed that Rh single atoms in the Rh-SAs/CeO

with high metal atoms utilization efficiency not only provided abundant active sites to promote the catalytic activity

but also suppressed the decomposition of HCOOH to CO and benefited the formation of HCOOH.
