Facilitating the reduction of V-O bonds on VO _x /ZrO₂ catalysts for non-oxidative propane dehydrogenation.

ABSTRACT: Supported vanadium oxide is a promising catalyst in propane dehydrogenation due to its competitive performance and low cost. Nevertheless, it remains a grand challenge to understand the structure-performance correlation due to the structural complexity of VO _x -based catalysts in a reduced state. This paper describes the structure and catalytic properties of the VO _x /ZrO₂ catalyst. When using ZrO₂ as the support, the catalyst shows six times higher turnover frequency (TOF) than using commercial γ-Al₂O₃. Combining H₂-temperature programmed reduction, in situ Raman spectroscopy, X-ray photoelectron spectroscopy and theoretical studies, we find that the interaction between VO _x
