Rh single atoms embedded in CeO2 nanostructure boost CO2 hydrogenation to HCOOH
文献摘要:
CO2 hydrogenation to value-added chemicals is a promising pathway to solve CO2-relevant environmen-tal problems but still remains a great challenge.Herein,we report a CeO2 nanostructure supported Rh single atoms(Rh-SAs/CeO2)catalyst and was used for the efficient CO2 hydrogenation to HCOOH.The Rh-SAs/CeO2 exhibited high catalytic activity with turnover numbers(TON)up to 221 at 200℃,which was 4-fold to that of CeO2 supported Rh nanoparticles(Rh-NPs/CeO2).Moreover,HCOOH selectivity for Rh-SAs/CeO2 reached 85%,much higher than that of Rh-NPs/CeO2(46%).Mechanism studies revealed that Rh single atoms in the Rh-SAs/CeO2 with high metal atoms utilization efficiency not only provided abun-dant active sites to promote the catalytic activity,but also suppressed the decomposition of HCOOH to CO and benefited the formation of HCOOH.
