A　series　of　LaNi1-xFexO3　(x　=　0.0,　0.2,　0.4,　0.7,　and　1.0)　perovskites　were　synthesized　and　characterized　by　X-ray　diffraction　(XRD),　N-2　physisorption,　scanning　electron　microscopy　(SEM),　H-2-temperature-programmed　reduction　(H-2-TPR),　and　X-ray　photoelectron　spectroscopy　(XPS).　The　perovskites　were　investigated　for　selective　catalytic　reduction　of　NOx　by　hydrogen　(H-2-SCR).　It　is　shown　that　Fe　addition　into　LaNiO3　leads　to　a　promoted　efficiency　of　NOx　removal,　as　well　as　a　high　stability　of　perovskite　structure.　Moreover,　easy　reduction　of　Ni3+　to　Ni2+　with　the　aid　of　appropriate　Fe　component　mainly　accounts　for　the　enhanced　activity.　Meanwhile,　deactivation　of　the　sulfated　catalysts　is　due　to　that　sulfates　mainly　deposit　on　active　Ni　component　while　doping　of　Fe　can　protect　Ni　to　some　extent　at　the　expense　of　partial　sulfation.　Copyright　(C)　2014,　Hydrogen　Energy　Publications,　LLC.　Published　by　Elsevier　Ltd.　All　rights　reserved.
