摘要

•Mn5Zr2Cr2.5Ox exhibited excellent low-temperature activity and H2O resistance.•Lewis acid sites and strong interactions among metal oxides improved H2O tolerance.•The adverse effects of H2O was caused by the competitive adsorption between H2O & NO.•Mn5Zr2Cr2.5Ox could be used as SCR catalyst for gas-fired boiler exhaust gases.
