Low-temperature　selective　catalytic　reduction(SCR)is　important　for　the　elimination　of　NOx　from　sta-tionary　sources.In　the　present　study,the　loading　of　Ce　and　W　on　α-Fe2O3　was　achieved　through　the　integration　of　single-mode　microwave　and　incipient　wetness　impregnation(IWI)methods.The　scanning　electron　microscopy(SEM)and　transmission　electron　microscopy(TEM)images　reveal　that　the　structure　of　α-Fe2O3　is　spindle-like,and　the　structure　remains　unchanged　after　the　introduction　of　Ce　and/or　W.The　results　of　NH3-SCR　investigation　demonstrate　that　NOx　conversion　over　Ce-W/α-Fe2O3　is　more　than　85％at　300℃,which　is　much　higher　than　that　over　Ce/α-Fe2O3　and　α-Fe2O3.Our　studies　illustrate　that　the　addition　of　Ce　can　significantly　increase　the　amount　of　surface　oxygen　vacancies　as　well　as　sites　of　moderate　basicity.On　the　other　hand,the　addition　of　W　can　obviously　decrease　the　amount　of　basic　sites　and　increase　the　number　of　Br?nsted　acid　sites.The　synergistic　effect　of　Ce　and　W　addition　on　balancing　acidity/basicity　properties　accounts　for　the　high　activity　of　Ce20W1o/α-Fe2O3　for　NOx　removal　at　low　temperatures.The　study　provides　insight　into　the　relationship　between　acidity/basicity　properties　and　catalytic　performance　of　Ce-W/α-Fe2O3　catalysts,which　is　beneficial　to　the　design　of　high-performance　NH3-SCR　catalyst　for　NOx　removal　at　low　temperatures.
