Iron‐doped ordered mesoporous alumina (meso‐FeAl) was synthesized through a “one‐pot” method and used in the synthesis of 1,3‐butadiene (BD) through the oxidative dehydrogenation of 1‐butene by using CO2 as a soft oxidant. X‐ray diffraction, N2 adsorption, and transmission electron microscopy results confirmed the ordered mesoporous structure of the meso‐FeAl catalyst with a high specific surface area and a large pore volume. The results also revealed that iron species were highly dispersed inside the alumina matrix. Relative to the Fe2O3‐impregnated meso‐Al2O3 catalyst and the conventional Fe2O3/γ‐Al2O3 catalyst, meso‐FeAl showed excellent catalytic activity, good stability, and high selectivity for the synthesis of BD. The structural properties as well as the form of the iron species existing in the meso‐FeAl matrix positively contributed to the performance of the catalyst.

“…Furthermore, CO 2 offers equilibrium conditions, improving ethylene selectivity, reducing coke formation, and maintaining longer catalyst life. Therefore, utilizing CO 2 is attractive and promising, as CO 2 can be used for the synthesis of valuable products rather than being released it into the atmosphere [44,53]. However, the use of CO 2 suffers from its inherent inertness with a Gibbs Energy of Formation of −394.4 kJ/mol [30].…”

Catalytic propane oxidative dehydrogenation (PODH) in the absence of gas phase oxygen is a promising approach for propylene manufacturing. PODH can overcome the issues of over-oxidation, which lower propylene selectivity. PODH has a reduced environmental footprint when compared with conventional oxidative dehydrogenation, which uses molecular oxygen and/or carbon dioxide. This review discusses both the stoichiometry and the thermodynamics of PODH under both oxygen-rich and oxygen-free atmospheres. This article provides a critical review of the promising PODH approach, while also considering vanadium-based catalysts, with lattice oxygen being the only oxygen source. Furthermore, this critical review focuses on the advances that were made in the 2010–2018 period, while considering vanadium-based catalysts, their reaction mechanisms and performances and their postulated kinetics. The resulting kinetic parameters at selected PODH conditions are also addressed.

“…Supported vanadia and chromia catalysts have been identified in recent studies as the most promising catalysts for ODH of lower alkanes by CO 2 . These catalysts are typically synthesized by incipient wetness impregnation of oxide supports such as SiO 2 , Al 2 O 3 , CeO 2 , and ZrO 2 by solutions of V V and Cr III precursors, such as ammonium metavanadate (NH 4 VO 3 ) and Cr III nitrate, followed by drying and thermal activation at about 350 °C in air to produce well‐dispersed, tetrahedrally coordinated molecular VO x and CrO x species on the surface of the oxide supports.…”

“…The catalytic activity and selectivity of these supported VO x and CrO x catalysts in lower‐alkane ODH is associated with the presence of monomeric and polymeric VO x and CrO x species at submonolayer surface coverage. Therefore, the catalytic behavior of these catalysts may be tuned by varying the surface coverage of VO x and CrO x species, the nature of the oxide support, and addition of promoter species …”

Carbon Dioxide as Feedstock in Selective Oxidation of Propane

Carbon dioxide is a promising nonconventional oxidant for catalytic dehydrogenation of lower alkanes to olefins. The lower catalytic activity of CO 2 compared to oxygen, which is typically used in oxidative dehydrogenation (ODH), also means that more reactive olefins are less likely to undergo undesirable combustion in the presence of CO 2 . Supported vanadia catalysts were synthesized by incipient wetness impreg- [a]
