英文摘要In this work, a new V-Mn bimetallic multifunctional catalyst based on SAPO-34 zeolite was constructed to achieve synchronous elimination of VOCs and NOx in denitrification zone conditions. The V-Mn/SAPO-34 catalyst exhibited excellent catalytic performance for toluene oxidation and NO reduction and remarkable flue gas tolerance compared to Mn/SAPO-34 and V/SAPO-34. The T90 (265 C) of V-Mn/SAPO-34 for toluene oxidation was 30 C and 125 C lower than that of Mn/SAPO-34 (295 C) and V/SAPO-34, respectively. Moreover, the conversion of NO could reach more than 90% at 138 C. Excellent catalytic activity of the V-Mn/ SAPO-34 was attributed to abundant hierarchical pores, oxygen vacancies and acidic sites owing to ion exchanges of SAPO-34. Meanwhile, the favorable V-Mn synergy effectively facilitated the electron transfer of catalytic reaction. In situ DRIFTS results indicated that the toluene oxidation over it followed the MvK mechanism, while the NH3-SCR followed the E -R mechanism, and the two, proceeding independently, did not interfere with each other during synchronous elimination.
