The promoting mechanism of in situ Zr doping on the hydrothermal stability of Fe-SSZ-13 catalyst for NH3-SCR reaction

Facile preparation, catalytic performance and reaction mechanism of MnxCo1−xOδ/3DOM-m Ti0.7Si0.2W0.1Oycatalysts for the simultaneous removal of soot and NOx

“…It should be noted that the active components of the catalyst were obtained by the incipient wetness impregnation method, so the number of active sites can be regarded as the result of all conversion of raw materials (Mn(NO 3 ) 2 and Co(NO 3 ) 2 ). [36][37][38] 3. Results and discussion…”

Effects of Catalyst Physicochemical Properties on the Catalytic Activity of Cu Zeolite Selective Catalytic Reduction at Different Inlet Gas Conditions

“…Zhang et al found that Mn showed considerable improvement in the low-temperature Cu-SAPO-34 activity. It was suggested that the excellent catalytic activity of Mn/Cu-SAPO-34 was ascribed to MnO 2 , which can promote “fast-SCR.” Chen et al found that the hydrothermal stability of Fe-SSZ-13 could be remarkably enhanced by Zr. A small amount of Zr addition was beneficial for improving the relative crystallinity of Fe-SSZ-13.…”

“…In terms of reaction conditions, the problem of the lowtemperature activity is solved by the rapid SCR reaction by adjusting the ratio of NO 2 /NOx. 27 Furthermore, a moderate increase of NH 3 /NOx ratio (ANR) can also improve NOx conversion at low temperatures.…”

Sustainable and Environmental Catalysis

“…As a matter of fact, it is worth highlighting some recent research advances. The oxidation of chlorinated compounds by catalytic combustion on non-noble metals based oxides [4,5], NO x reduction to nitrogen or by selective catalytic reduction (SCR) with ammonia in the presence of heterogeneous catalysts [6]; biofuel production from vegetable oils [7]; the development of new active catalysts for Fenton and photo-Fenton processes [8]; the development of supported nanoparticle catalysts for the treatment of the emission of harmful substances from automobiles, and the use of waste as source of metals for catalysts preparation [9]; the design of new active catalytic systems for the preparation of olefins from polyols [10]; the catalytic hydrotreatment in the valorization of bio-oils obtained from lignocellulosic biomass pyrolysis [11]; and the design of active catalysts for the preparation of organic carbonates from CO 2 or bio-based compounds are some examples in this framework [12,13].…”
