Er composition (X)-mediated catalytic properties of Ce1-XErXVO4 surfaces for selective catalytic NOX reduction with NH3 at elevated temperatures

Jongsik Kim et al.

Summary: Rare earth metal vanadates have shown promise for converting NOX to N-2 at high temperatures, but face limitations in catalytic activity due to weak hydrothermal stability, low N-2 selectivity, and limited active sites. This study demonstrates the efficacy of structurally modifying vanadate with additional rare earth metals to generate bimetallic vanadates with improved reactivity and stability.

Supercritical Carbon Dioxide Extraction-Mediated Amendment of a Manganese Oxide Surface Desired to Selectively Transform Nitrogen Oxides and/or Ammonia

Jongsik Kim et al.

Summary: The study demonstrated that supercritical CO2 extraction can adjust the quantities/strengths of surface sites on Mn oxide, improving the selectivities to desired N-2 and promoting SO2 tolerance. The mechanism involves promoting unique NOx reduction pathways to produce N-2 only while detouring undesired byproducts, and tailoring redox sites to deter NH3 oxidation. Additionally, Mn-CO2 showed enhanced long-term stability in reducing NOx over Mn in the presence of SO2 at lower temperatures, providing higher selectivities to desired N-2.

Tailoring Lewis acidic metals and SO4 2?functionalities on bimetallic Mn-Fe oxo-spinels to exploit supported SO4?? in aqueous pollutant fragmentation

Jongsik Kim et al.

Summary: The generation of SO4?? anchored on metal oxides through radical transfer is promising for decomposing refractory contaminants in water. By adjusting the metal compositions and Lewis acidic strength, the production of SO4?? can be optimized to increase the degradation rate of pollutants.

Summary: This study demonstrates the importance of rare-earth metals in HSOA-/SOA2-/H3-BPO4B--modified RMVO4 frameworks, with properties and SCR performance varying significantly depending on the choice of RM element. The RM-P catalysts outperformed the RM-S analogues in accelerating SCR at lower temperatures, while the opposite trend was observed at higher temperatures.
