Abstract

An environmentally benign Cu–Ce–Ti oxide catalyst exhibited excellent NH₃-SCR activity, high N₂ selectivity and strong resistance against H₂O and SO₂ with a broad operation temperature window. The dual redox cycles (Cu²⁺ + Ce³⁺ ↔ Cu⁺ + Ce⁴⁺, Cu²⁺ + Ti³⁺ ↔ Cu⁺ + Ti⁴⁺) play key roles for the superior catalytic deNO_x performance.
