The effect of aluminothermic reaction on the progress of carbothermic reaction in simultaneous mechanochemical reduction of CuO and ZnO

CuOx/CeO2 catalyst derived from metal organic framework for reverse water-gas shift reaction

“…But the behavior during the reduction treatment is opposite, as it produces a strong surface segregation of copper in the former, and an important decrease of the surface Cu content in the catalyst obtained under oxidative pyrolysis. As reported by other authors, [34,37] this surface migration of ceria is indicative of a strong metalsupport interaction effect. It is clear for the catalytic results we have obtained with these catalysts that the induction of this strong copper-ceria interaction is crucial in the reverse water-gas shift reaction.…”

Combination of mechanochemical activation and self-propagating behavior for the synthesis of nanocomposite Al2O3/B4C powder

“…This fact, quick transformation observed by XRD analysis (Fig. 1) and high T ad calculated by thermodynamic relations (Table 3) Some researchers reported that by increasing the milling time, the exothermic aluminothermic reaction provided the required heat for the carbothermic reactions [25,26]. As can be seen, the TG curve does not show any significant change in the sample weight after 200 • C, and this indicated that there is no gas (CO or CO 2 ) emission during the combustion synthesis.…”

Development and characterization of CoAl–Al2O3 intermetallic matrix nanocomposite

“…The adiabatic temperature, T ad , for displacement Reaction (2) was calculated to be 3753.3 K, and according to Merzhanov's criteria (T ad > 1800 K) [22] and even Schaffer and McCormick criteria (T ad > 1300 K) [23], SHS reaction is predicted in this system. Therefore, it is most probable that the heat produced by the aluminothermic reaction is sufficient to activate the CoAl formation.…”
