摘要

•RWGS performance increased: Cu/SiO2 < Cu-Fe/SiO2 << Cu/Fe-SiO2 Nanocomposites (FSN).•Strong Cu-FSN interactions affected the catalyst reducibility and Cu0:Cu2O surface ratio.•Improved Cu/FSN rate was related to superior Cu0 fractions and surface basicity’s.•Fe-species improved CO selectivity and resistance against deactivating carbonaceous species.
