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.

Implication

Catalysts with TiO2 {001} facets show enhanced NOx-SCR properties, indicating the role of dispersion.

Abstract

Owing to the lower vacancy density and more negatively charged O 2− on TiO 2 {001}, the V 2 O 5 /TiO 2 -NS{001} catalyst exhibits better NO x -SCR performance.
