Selective catalytic reduction of NO by NH3 over V2O5-WO3 supported by titanium isopropoxide (TTIP)-treated TiO2

High-Dispersed V2O5-CuOX Nanoparticles on h-BN in NH3-SCR and NH3-SCO Performance

“…NO X is a compound of nitrogen and oxygen, including NO, NO 2 , N 2 O, and N 2 O 3 ; it can result in ozone layer depletion, greenhouse effect, photochemical smog, and acid rain. Accordingly, various environmental protection regulations have been strengthened, and NO X emission standards have become more stringent [2,3]. Generally, most NO X emissions originate from combustion in stationary, such as coal-fired power plants [4,5].…”

Modelling of Selective Catalytic Reduction of NO_x with NH₃ over the Fe-Cu/ZSM-5 Catalyst

“…

The selective catalytic reduction (SCR) of NO x with NH 3 is currently the most effective technology established for the abatement of NO x emissions from stationary sources [1]. In the flue gas, NO x (about 95% NO) react with O 2 and injected NH 3 according to the following equation:Commercial catalysts, in the form of honeycomb monoliths, are composed of an anatase TiO 2 carrier supporting the active components, namely, V 2 O 5 and WO 3 (or MoO 3 ) for the flue gas at a temperature of 300 to 400ºC [2,3].However, due to the biological toxicity of V 2 O 5 to humans and the environment, the narrow operation temperature window (300-400ºC), and the undesired
