Ordered mesoporous TiO2 framework confined CeSn catalyst exhibiting excellent high activity for selective catalytic reduction of NO with NH3 at low temperature

Boosting Water-Resistance Ability on a PTFE Modified Ti-OMS-2 Catalyst for Low-Temperature NH3-SCR Reaction

“…Before the reaction, the catalyst was treated with NO and O 2 for 30 min (Figure S8b). Typically, the bridged nitrite (1550 cm –1 ), bidentate nitrate (1287, 1325 cm –1 ), trans -(N 2 O 2 ) 2– (1078 cm –1 ), and gaseous NO 2 molecules (1634 cm –1 ) could be detected on the Ti-OMS-2-20%-PTFE catalyst surface. , High-purity nitrogen was used to purge for 10 min before ammonia was injected, and then the evolution of the spectra was recorded with time (Figure b). As shown in Figure b, adsorbed NO 2 species (1634 cm –1 ) disappeared within 5 min, suggesting that it seemed to participate in the reaction.…”

Unveiling a remarkable enhancement role by designing a confined structure Ho-TNTs@Mn catalyst for low-temperature NH3-SCR reaction

“…This might be a consequence of stronger interactions between the active intermediates or changes to the crystalline structure of the catalyst. 30…”

“…This might be a consequence of stronger interactions between the active intermediates or changes to the crystalline structure of the catalyst. 30 The valence distribution of Ho for the fresh and deactivated catalysts is shown in Fig. 4c.…”

Significant Enhanced SO2 Resistance of Pt/SiO2 Catalysts by Building the Ultrathin Metal Oxide Shell for Benzene Catalytic Combustion

“…Mu et al prepared ordered mesoporous CeSnO x /TiO 2 -E catalysts with a skeleton-confined effect via the evaporation-induced self-assembly strategy. 24 It was found that the catalyst exhibited excellent thermal stability.…”

“…The above results showed that the confined effect of the pore promoted the high dispersion of Co 3 O 4 , and the nanoparticles were confined in the pores of ordered mesoporous SiO 2 . Mu et al prepared ordered mesoporous CeSnO x /TiO 2 -E catalysts with a skeleton-confined effect via the evaporation-induced self-assembly strategy . It was found that the catalyst exhibited excellent thermal stability.…”
