•Co/ZnO catalysts with different fractions of ZnO (10–10) facets were prepared.•Different cobalt reducibility was observed on ZnO (0001/000-1) polar and ZnO (10–10) nonpolar facet.•ZnO (10–10) facet stabilized metallic Co for WGS leading to high CO2 yield.
The effects of ZnO facets on ethanol steam reforming (ESR) were investigated over Co/ZnO catalysts synthesized using ZnO with different fractions of (10–10) non-polar facet. Co supported on ZnO with a higher fraction of (10–10) non-polar facet shows higher C–C cleavage activity and higher selectivity to CO2 (lower selectivity to CO) compared with Co supported on ZnO with less (10–10) non-polar facet exposed. The improved ethanol steam reforming performances are attributed to the high fraction of metallic Co stabilized by the ZnO (10–10) non-polar facet, which enhanced C–C cleavage and water-gas-shift (WGS) activities.
