ABSTRACT Promoting the collaborative treatment of nitrogen oxides (NO x ) and volatile organic compounds (VOCs) has become an important research direction for multi‐pollutant control (MPC). NO chlorobenzene (CB) were selected as substitutes to study related properties supported vanadium‐titanium (V‐Ti)‐based catalysts, high‐efficiency composite multi‐metal oxide catalysts screened out. The results indicated that addition Ce, Mn, Fe elements could improve denitration catalytic oxidation activity CB. V(3)Ce(5)/Ti had better due formation more oxygen vacancy structure. Denitration removal can reach than 95%. efficiency at 280 °C was investigated under different working conditions. conversion frequency (TOF) CB on catalyst surface follows: CBCO+NO 2 >CBCO>CBCO+NO>CBCO+NH 3 . water sulfur resistance steam inhibited performance catalyst, but promoted CB, reaction reversible. Sulfur dioxide (SO significantly synergistic caused irreversible reaction.
