Vanadate is a particular class of intriguing, emerging catalytic phase proper to reduce NOX with NH3 at low temperatures (SCR). The vanadates are given a spectrum of binary phase diagrams constituting of metal (M) oxides and V2O5, by which the coordination numbers or geometries of M/V can be readily modulated upon the change in the stoichiometries defined in a specific vanadate (e.g., CuXV2OX+5, where X=1, 2, 3, and 5). In this presentation, we showcase our study on ‘how catalytic property of the vanadate can be tuned by altering its stoichiometry and bring about distinct SCR consequence at low temperatures’. A host of characterization techniques served to clarify the dissimilar traits of the vanadate surfaces, which were related to their SCR performance in terms of NOX conversion, N2 selectivity, longevity, etc. |
