Abstract
Transformation of surface nitrates under CH4 (CH4 + O-2) was found to ensure steady-state activity of Co-ZSM-5 in the selective catalytic re duction of nitrogen oxides by methane (CH4-SCR). For Cu-ZSM-5, such sp ecies are mainly converted into NO. Relaxation of the coordination sph ere due to oxygen and NO adsorption, stability of C,N-containing inter mediates and activation routes of hydrocarbons (methane, propane) were analyzed as factors determining catalytic properties of Cu and Co cat ions.
