Herein, we propose a simple approach to synthesize a highly active Pt20Fe/CeO2 catalyst employing the borohydride reduction process. Transmission electronic microscopy revealed monodispersed 2.8 nm-Pt nanoparticles on CeO2, and the role of Fe species on the activity is discussed. The excellent CO conversion of 99.6% and CO2 selectivity of 92.3% carried out at ambient temperature meet the CO-PROX requirements for an adequate supply of hydrogen in fuel cell device.17751-17762openAccessnanoparticlesplatinumcatalystsironcarbon monoxideoxidationhydrogenfuel cellsborohydridesArtigo de periódico344610.1016/j.ijhydene.2021.02.1920000-0002-7011-8261https://orcid.org/0000-0002-7011-826172.6888.00
