It is thoroughly demonstrated from Tong, Y et al's work that abundant strongly electronegative fluorine (F) anions confined into 3D nickel foam are a perfect platform for probing the role of fluorine anion in the oxygen evolution reaction process. So, it was found that Ni foam 3D network structure might be beneficial for fluorine incorporation and the powerful electronegativity of F anion is favorable to construct weak metal-fluorine bonds, which is easy for surface reconstruction to form active species of hydroxides/oxides, thus subsequently increasing its OER catalytic performance. Indeed, as fully described in Fig. ), the incorporation of fluorine ions into Ni foam plays a key role to tune the electrochemical properties of Ni-based electrodes for energy conversion and storage applications. Also, Fig. ) demonstrates better stability of the proposed electrode material (F-NiAl LDH-NF) over 12 hours of electrochemical stability processing at 0.3V. Therefore, it is suggested that this strategy might be extended to numerous other Ni-based materials for designing highly active, selective, and stable metal electrodes. Nickel oxides have been embedded over uniformly and highly nitrogendoped carbon nanofibers (N-CNFs) as highly active catalysts for methanol oxidation reaction under alkaline conditions as described in Al-Enizi, A.M et al's research article . (N-CNFs) was obtained through electrospinning of a solution mixture of (polyacrylonitrile, polyaniline, and graphene) followed by heat treatment at 1200°C. Subsequently, Nickel oxides (NiO) catalyst was charged over (N-CNFs) via chemical precipitation of Ni(OH)2 followed by annealing at 400°C. So, it can be assumed that due to interesting properties of N-CNFs such as high electrical conductivity, the high surface area of 440 m 2 g -1 , and the small particle size of NiO catalyst (7.0 to 8.0) nm, it appears that the resulting synergistic effect leads to the higher catalytic activity of NiO/N-CNFs for the methanol oxidation under alkaline environment over other many nickel-based catalysts. Hence, it is summarized that N-CNFs obtained through (polyacrylonitrile, polyaniline, and graphene) composite might be considered a gifted candidate as a fully active catalyst support material. Moreover, pure ultrafine nickel nanoparticles (2.3 ± 0.4) nm have been anchored on rGO for the catalytic oxidation of methanol as highlighted in
