Abstract

•The Fe2O3 in fly ash slowed down the inhibitory effects of water vapor on Hg0 removal efficiency over Ce/SC.•H2O molecules dissociated on Fe2O3 surfaces to generate Fe-OH groups.•The formation of Fe-OH groups is thermodynamically more favored in γ-Fe2O3 than α-Fe2O3.•The Fe-OH groups had promoting effects on Hg0 removal efficiency.
