“…Hydrogen has been remarkably spotlighted recently as clean energy due to its high efficiency with low emissions of greenhouse gases through a fuel cell application compared to conventional fossil fuel-based energies [1]. Moreover, since the emission regulations are getting stricter in regard to not only power generation but also vehicles, the needs of clean fueled vehicles, such as electric or fuel cell vehicles, are more attractive compared to the conventional fossil fuel combusting vehicles.…”

The synergetic effects of Co oxides on the Ni/CoAl (NCA) catalysts were observed at an optimal molar ratio of Al/Co = 2 (NCA(2)) due to the partial formations of thermally stable spinel CoAl2O4 phases for the steam reforming of propane (SRP). The optimal content of the spinel CoAl2O4 phases on the NCA(2) was responsible for the formation of the relatively active oxophilic metallic Co nanoparticles with a smaller amount of less active NiAl2O4 on the surfaces by preserving the relative amount of metallic Co of 68% and 52% in the reduced and used catalysts, which enhanced the catalytic activity and stability with the largest specific rate of 1.37 C3H8/(Ni + Co)h−1 among the tested NCA catalysts. The larger or smaller amounts of Co metal on the less active NCA mainly caused the preferential formation of larger aggregated Ni nanoparticles ~16 nm in size due to their weaker interactions, or induced the smaller formations of active metal phases by selectively forming the spinel NiAl2O4 phases with ~60% in the NCA(4), resulting in a fast deactivation.

“…Nevertheless, there are several side reactions which could lead to the production of compounds such as CH 4 , C 2 H 4 O, C 2 H 4 , C 3 H 6 O (among others), and therefore, affect the expected hydrogen yield. Literature reports reveal that ethanol conversion and selectivity to hydrogen strongly depend on the nature of the metal and the support, the type of precursor, the preparation methods, the presence of additives and the operating conditions [1].…”
