Selective catalytic reduction of nitric oxide with ammonia over zirconium-doped copper/ZSM-5 catalysts

•Zirconia introduction favors copper dispersion and inhibits copper crystallization.•Zirconia addition is beneficial to enriching copper species on the ZSM-5 surface.•The interaction between copper and zirconium enhances the lattice oxygen and site reducibility.•The Cu-Zr/ZSM-5 presents a wide activ...
