Why Boron Nitride is such a Selective Catalyst for the Oxidative Dehydrogenation of Propane.

Angewandte Chemie, 2020
In recent years, boron-containing materials and in particular boron nitride, have been identified as highly selective catalysts for the oxidative dehydrogenation of alkanes such as propane.

Highly efficient and robust Cu catalyst for non-oxidative dehydrogenation of ethanol to acetaldehyde and hydrogen

, 2020
While acetaldehyde is industrially produced in the Wacker process by homogeneous catalysts, a heterogeneous catalyst is so far elusive due to rapid deactivation stemming from metal sintering and coke formation.

Isolated Indium-hydrides in CHA Zeolites: Speciation and Catalysis for Non-oxidative Dehydrogenation of Ethane.

Journal of the American Chemical Society, 2020
Study of the formation, characterization, and functionality of isolated surface hydrides on solid materials is a formidable task because of the complexity of solid surfaces and the difficulty of analyzing structure in solids.

Coverage-dependent Behaviors of Vanadium Oxides for Chemical Looping Oxidative Dehydrogenation.

Angewandte Chemie, 2020
Chemical looping provides an energy and cost effective route for alkane utilization. However, there is considerable CO 2 co-production caused by kinetically mismatched O 2- bulk diffusion in current chemical looping oxidative dehydrogenation systems ...

Oxidative dehydrogenation of light alkanes to olefins on metal-free catalysts.

Chemical Society Reviews, 2020
Metal-free boron- and carbon-based catalysts have shown both great fundamental and practical value in oxidative dehydrogenation (ODH) of light alkanes. In particular, boron-based catalysts show a superior selectivity toward olefins, excellent stability ...

Oxidative dehydrogenation of propane using layered borosilicate zeolite as the active and selective catalyst

Journal of Catalysis, 2020
Oxidative dehydrogenation (ODH) of propane to propylene offers a promising large-scale alternative to direct dehydrogenation. The reported metal oxides catalysts generally cause over-oxidation of propylene to COx, thus hindering the commercialization of ...

Generalized Mechanistic Framework for Ethane Dehydrogenation and Oxidative Dehydrogenation on Molybdenum Oxide Catalysts

ACS Catalysis, 2020
Ethane turnovers to ethylene in either oxidehydrogenation with diverse oxidants (O2, CO2, H2O) or dehydrogenation (without an oxidant) over two-dimensional MoOx dispersed on Al2O3 catalyst occur vi...

Modulating Lattice Oxygen in Dual-functional Mo-V-O Mixed Oxides for Chemical Looping Oxidative Dehydrogenation.

Journal of the American Chemical Society, 2019
Oxygen chemistry plays a pivotal role in numerous chemical, energy and environmental systems. Particularly, selective cleavage of C-H bonds by metal oxo species is highly desirable in the catalytic dehydrogenation of light alkanes.

Graphitic carbon nitride catalyzes selective oxidative dehydrogenation of propane

, 2020
Exothermic oxidative dehydrogenation of propane (ODHP) to olefins is a promising alternative to industrialized direct dehydrogenation. However, it encounters a great challenge to control the olefin selectivity as the over-oxidation to produce carbon ...
