Hydrotalcite‐based materials are preferred as catalysts due to their versatility and easiness of their synthesis. This work studies supported nickel catalysts made from hydrotalcites through sol‐gel synthesis, Ni‐EDTA impregnation, and coprecipitation. The synthetized hydrotalcites present nanocapsular morphology and dispersed nickel nano‐oxide particles after calcination at 500 °C. The catalysts were evaluated at 600 °C and 800 °C for 8 hours and demonstrated high conversions and varying yields, with sol‐gel oxide catalysts (SgOxMix) showing the best performance with the highest reactivity and controlled coke formation at 800 °C after 14 hours of testing. The mixed oxide morphology promotes electronic effects and inhibits carbon encapsulation of metallic particles. Principal component analysis was performed to explain fluctuations in the reaction pathway.

“…A considerable amount of work was carried out for the promotion of selectivity to propylene during the ODHP by different methods. It was reported that alkali metal additives could enhance the selectivity to propylene in the ODHP on MoO 3 /TiO 2 , V 2 O 5 /TiO 2 [10,11] , V 2 O 5 / Al 2 O 3 [12] and V 2 O 5 /SiO 2 , V 2 O 5 /MgO [13][14][15] catalysts; the effect was explained by the modification of the acidbase properties of the catalysts with the alkalis. In the studies of Kondratenko and coworker, the ODHP reaction over VO x /γ-Al 2 O 3 [16] and VO x /MCM-41 [17] catalysts indicated that the propylene selectivity could be boosted when replacing O 2 using N 2 O, suggesting that the enhanced ODHP performance with N 2 O resulted from the lower ability of N 2 O to enable the re-oxidation of the reduced VO x species, i.e., the reduction degree of catalyst in the presence of N 2 O is higher than that in the presence of O 2 [18] .…”

High-surface-area mesoporous Ce x Zr 1-x O 2 materials synthesized through a surfactant-assisted approach of nanocrystalline particle assembly are utilized as a promising support for VO x -based catalysts. The catalytic properties of the resultant VO x /Ce x Zr1x O 2 nanocatalysts are evaluated by the oxidative dehydrogenation of propane using a microreactor-GC system. It is indicated that the catalyst particles are on a nanoscale, having a mesoporous structure with uniform pore-size distribution and high surface area. The catalytic behavior of these mesoporous nanostructured VO x /Ce x Zr1x O 2 catalysts for the oxidative dehydrogenation of propane reaction relies on the vanadia loading amount, the calcination temperature, the surface area and the Ce/Zr ratio of the supports, the particle size of active compounds, and the additional contribution to the propylene formation derives from the contribution of the catalytic dehydrogenation of propane under oxygen-lean conditions. The catalyst prepared with 8 wt% vanadia loading on Ce 0.2 Zr 0.8 O 2 exhibits high and stable catalytic performance in the oxidative dehydrogenation of propane reaction.
