Infrared spectroscopic characterization of the oxidative dehydrogenation of propane by V4O10+ [PDF]

International Journal of Mass Spectrometry, 2010
Abstract The gas phase reaction of V4O10+ with propane is studied by infrared photodissociation spectroscopy combined with density functional calculations. Mass-selected V4O10+ clusters react with propane under thermalized, multiple collision conditions in a buffer gas filled ion trap at 100 K.

Propane oxidative dehydrogenation on VO /ZrO2 catalysts

Journal of Catalysis, 2004
Abstract The catalytic properties of the V 2 O 5 /ZrO 2 system for the oxidative dehydrogenation of propane were studied. Catalysts with different chemical compositions (i.e., vanadium oxide loadings) were prepared, with activation done by calcination at two temperature levels.

Flavin Catalysts in Organic Synthesis

Angewandte Chemie, EarlyView.
Flavins and their congeners are potent catalysts for organic synthesis inspired by enzymatic transformations. In addition to catalysis in the flavin ground state via covalent intermediates, the excited singlet and triplet states unlock applications including photooxidation, photoreduction, and energy transfer via sensitization.

Joule self‐heating enabled oxygen transport and coupled methane reactions in a La0.6Sr0.4Co0.2Fe0.8O3‐δ hollow fiber membrane reactor

AIChE Journal, EarlyView.
Abstract Mixed‐conducting ceramic hollow fiber membranes are a versatile platform for oxygen separation, value‐added chemical production, and oxy‐combustion. Because oxygen permeation is thermally activated, these systems typically rely on bulky, energy‐intensive furnaces that suffer from low efficiency and large thermal inertia.

Hole‐Activated Lattice Oxygen Enables Pt‐Free Propane Dehydrogenation by Eliminating the Hydrogen Recombination Bottleneck

Angewandte Chemie, Volume 138, Issue 40, 28 September 2026.
Trace Mg doping into gallia–alumina generates hole‐type oxygen species that accelerate hydrogen recombination, eliminating the need for Pt promotion. The fully oxide‐based catalyst resists sintering under repeated regeneration, outperforming benchmark PtSn and CrOx catalysts with exceptional stability over 30 dehydrogenation–regeneration cycles ...
