摘要

•α-Fe2O3 nanocrystals with clean (113), (104), and (102) facets exposure.•(113) facets show higher reactivities to EB dehydrogenation in the presence of CO2.•The adsorption behavior of CO2 on different facets results in different activities.•O (III) on α-Fe2O3 is favorable for the adsorption and activation of CO2.
