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.
Abstract
Owing to the lower vacancy density and more negatively charged O 2− on TiO 2 001, the V 2 O 5 /TiO 2 -NS001 catalyst exhibits better NO x -SCR performance.
