As already known, noble metals-based catalysts such as Rh, Ir, Pd, and Pt deserve excellent catalytic behavior for many catalytic processes, including both oxidation/reduction, hydrolysis/Hydrogenation, and so forth. For example, Pt-based catalysts exhibit excellent catalytic activity for hydrogen oxidation reactions (HOR). But unfortunately, noble metal-based catalysts show considerably reduced activity in alkaline media than in acid media. Moreover, adding the fact of their rare nature, high cost, and subjective to poisoning species, researchers are focusing to develop new materials with high catalytic performances and as well as affordable costs for several issues including HOR, other fuels oxidation, and so forth. In the same way, Zhou, Z et al carefully reviewed 2020 the recent development of non-precious Ni-based catalysts for HOR in alkaline media. In this particular study, they paid attention, especially to Pt-group metal catalysts, and Ni-based catalysts for HOR including (Ni-oxides catalysts, multimetallic Ni-based catalysts, and nickel catalysts loaded on supports). Indeed, it is noticed that up to date, the distinctive un-precious HOR metal catalysts are Ni-based nanomaterials. Also, both elementary steps and vital activity parameters for a HOR were introduced. The development of Ni(OH)2-Ni/C as a catalyst for catalytic oxidation of hydrogen in alkaline media has been described in Pan, Y et al's research article . In fact, it is physicoelectrochemically proved that the catalyst with the surface molar ratio of Ni(OH)2/Ni (1.1:1) possesses higher catalytic performance as high as 6.8 times of that Ni/C. Therefore, Ni(OH)2-Ni/C catalyst showed good catalytic stability toward HOR. Recently, Jiang, S et al supported Ni NPs over carbon nanosheets with tunable N doping gratified as an active material for the hydrogen oxidation reaction (HOR). It discovered that the synthesized catalyst with appropriate N-doping content of 8.7 at% reaches the optimal HOR catalytic performance with a measured current density of 1.8 mA/cm 2 at an overpotential of 80 mV vs RHE, which is among the most powerful un-precious metal HOR catalyst. It also showed high catalytic kinetics towards the hydrogen oxidation reaction. In 2020, Oshchepkov, A.G et al carefully paid attention to the recent progress in the understanding of Ni-based catalysts for alkaline oxidation of hydrogen-containing fuels. Details of the electrochemical performance of Ni-based catalysts in alkaline conditions and methodologies to define the active surface area of these catalysts were discussed. Also, the electrocatalytic activities of Ni-based
