NO x abatement has been an indispensable part of environmental catalysis for decades. Selective catalytic reduction with ammonia using V 2 O 5 /TiO 2 is an important technology for removing NO x emitted from industrial facilities. However, it has been a huge challenge for the catalyst to operate at...
