The dispersion state and NOx-SCR properties of VOx species on V2O5 catalysts with different preferentially exposed facets of TiO2 supports

Key Points

• The V2O5/TiO2-{001} catalyst shows significantly better NOx-SCR performance due to its unique features.
• With lower vacancy density and a more negatively charged O2−, the catalyst enhances activity metrics for NOx reduction.
• Experimental investigations focused on the dispersion properties of VOx species across different TiO2 facets.
• Understanding specific facet effects may enable advancements in catalyst design for environmental applications.
