Abstract Nitrogen oxides (NO_x) are critical atmospheric pollutants that severely threaten both the environment and human health. Conventional vanadium-titanium (V-Ti) catalysts exhibit high activity in the range of 300—400 ℃, but their insufficient performance at lower temperatures restrict large-scale application in flue gas purification. In this work, a cerium-modified vanadium-based oxide catalyst was prepared using a vanadium metal organic framework (V-MOF) precursor through an impregnation-pyrolysis strategy. The introduction of Ce markedly enhanced the low-temperature NH₃-SCR activity, achieving a NO_x conversion of up to 95.3% with nearly 100% N₂ selectivity. Structural analysis revealed that the catalyst mainly consists of V₂O₅ and CeVO₄, where the coexistence of multiple valence states of V and Ce facilitates redox cycling, while the increased surface acidity promotes reactant adsorption. This study demonstrates a rational modification approach for designing efficient V-based catalysts with excellent low-temperature activity, offering considerable potential for practical NO_x removal.

Key words： low-temperature NH₃-SCR NO_x removal V-based catalyst Ce doping metal-organic framework (MOF) CeVO₄
