Summary: The study found that partial substitution of zirconium for praseodymium in a ceria-zirconia support can enhance the support reducibility, but impregnation of niobium and tungsten inhibits the redox behaviors. Additionally, niobium and tungsten provide acidic sites while praseodymium inhibits ammonia storage and decreases deNO(x) performances. The various redox and acidic behaviors observed in the studied materials demonstrate a strong competition between NOx SCR and NH3 oxidation pathways.

Summary: Selective catalytic reduction by methanol (Methanol-SCR) is a promising technology for treating exhaust with high concentration of sulfur. A new catalyst of nano-bismuth oxide implanted FER zeolites (Bi-FER) has been successfully synthesized, showing a lower optimum reaction temperature compared to existing technology. The reactivity of methyl groups generated on Brønsted acid sites neighboring with nano-bismuth oxide has been found to be highly effective for NOx removal. Therefore, a strategy of methanol activation to produce reactive methyl groups has been proposed for improving Methanol-SCR catalysts.

Summary: The production of spent honeycomb V2O5-WO3/TiO2 catalysts has caused serious environmental hazards. This study focused on the changes of typically spent catalysts from pulverized coal (PC) and circulating fluidized bed (CFB) boiler deNOx systems, including morphologies, pore structure, chemical composition, carrier, and active components properties. The major deactivation factors were pore blockage caused by fly ash and sulfur deposition, with CFB catalysts being more easily deactivated due to severe pore structure loss. The transformation of anatase to rutile TiO2 and the shift in valence state of V were major contributors to irreversible deactivation. This research provides valuable insights into the deactivation mechanism and potential recycling of spent catalysts.

Summary: A novel 3D-structured Mn/YTiOx nanotube catalyst was designed and its catalytic performance for NH3-SCR reaction at low temperature was investigated. The results showed that an appropriate amount of Y doping improved the dispersion of MnOx and increased the concentration of active sites, thus enhancing the activity, N-2 selectivity, and resistance to H2O/SO2 of the catalyst. The Mn/3%YTiOx catalyst exhibited the highest activity with over 90% NO conversion and N-2 selectivity in a wide temperature range from 120 to 320 ℃.

Summary: In this study, the researchers investigated the reduction/oxidation half-cycles of the selective catalytic reduction of NO with NH3 at 200 degrees C using in situ and operando spectroscopies. They proposed a general mechanism that is applicable to both V and Cu catalysts, where N-2 and H2O are formed during the reduction half-cycle and the regenerated V(V) or Cu(II) sites react with surface H+ to produce H2O during the oxidation half-cycle. The results provide comprehensive evidence of the general mechanism of NH3-SCR.

Summary: A comparative investigation of Ru-based catalysts on different supports for catalytic combustion of dichloromethane was conducted, revealing that Lewis acid sites were more active than Brønsted acid sites. The presence of Cl species on TiO2 and Al2O3 supports interacted strongly with Lewis acid sites, leading to the formation of more polychlorinated toxic by-products. The study provides valuable insights into the development of catalytic combustion catalysts for chlorinated volatile organic compounds.

Summary: In this study, a novel heterostructured SrTiO3/SrCO3 (STO/SCO) interface was constructed via a one-pot g-C3N4 (CN) self-sacrificing hydrothermal strategy. The as-developed STO/SCO photocatalyst showed high degradation rates for NO and HCHO in continuous-flow reactors. The presence of CN in the crystallization process as the source of CO32- enabled the formation of the STO/SCO interface. Additionally, enhanced chemisorption effects of O-2 on the catalyst surface were observed, leading to photocatalytic oxidation under simulated solar light.

Summary: The conventional V2O5-WO3/TiO2 catalyst is significantly poisoned by arsenic, resulting in a loss of catalytic activity. The doping of Al or Mo has been found to promote the arsenic resistance in NH3 selective catalytic reduction (NH3-SCR), but the mechanism behind this promotion is still debated. Our experimental and theoretical studies reveal that arsenic species preferentially adsorb on Al or Mo, forming arsenates and avoiding bonding with the active V sites. Furthermore, Al doping reduces the mobility of near-surface and bulk lattice oxygen, while Mo doping enhances MPC activity and COx selectivity through vanadyl polymerization and an enriched V5+ state.

Summary: In this study, Cu-Ce/TS-am catalysts were synthesized to enhance the catalytic activity and water resistance for low-temperature NOx reduction with ammonia. The optimized Cu-Ce/TS-am sample achieved over 90% NOx conversion at 180-350 degrees C in the presence of water. The addition of Si improved specific surface area, total acidity, and oxygen mobility, promoting SCR activity. Moreover, alkali treatment optimized the mesoporous pore structure and increased the exposure of active sites and acidic sites, further enhancing water resistance and catalytic activity. These findings provide useful guidelines for developing highly active and water-resistant SCR catalysts in real applications.

Summary: This study investigates the relationship between the morphology of PMMA monopolymers and PMMA-PHEMA copolymers with the expected nature of surfactant-free microemulsions (SFMEs) before polymerization. It is found that previously mesostructured, surfactant-free mixtures can produce porous polymers of different morphologies, while unstructured, oil-rich regions lead to solid, transparent polymers without nanostructured morphologies. Additionally, a surfactant-based reference system shows similar phase behavior and polymer morphologies as the comparable surfactant-free system, indicating the importance of the hydrotropic behavior of HEMA in this system.
