Recent advances in non‐precious Ni‐based promising catalysts for water splitting application

“…118 Raut et al obtained a carbonaceous electrode material in vertically grown nanosheets formed via coconut water onto 3D-Ni-foam as C@Ni-foam, which evidenced OER and HER over potentials of activity with 219 and 122 mV, respectively, and 27 and 53 mV dec À1 Tofel slopes, suggested a bifunctional efficacy of electrode materials and synthesis method, ie, spray pyrolysis. 119 120 Further, honeycomb-like heterostructure fabricated by a threestep electrodeposition/dealloying/electrodeposition strategy was composed of NiFe shell and Ni(Cu) nanotubes, as an efficient and robust bifunctional electrocatalyst for overall water splitting. 3 The as-prepared NiFe@Ni(Cu)/ NF bifunctional catalyst adduced extremely low and competitive overpotentials to achieve a current density of 10 mA cm À2 for HER and OER.…”

“…Gao et al used the electrodeposition process to synthesis the NiSe/Ni‐foam to check HER as well as OER performance where 190 and 136 mV overpotentials respectively were documented at 100 mA/cm 2 118 . Raut et al obtained a carbonaceous electrode material in vertically grown nanosheets formed via coconut water onto 3D‐Ni‐foam as C@Ni‐foam, which evidenced OER and HER over potentials of activity with 219 and 122 mV, respectively, and 27 and 53 mV dec −1 Tofel slopes, suggested a bifunctional efficacy of electrode materials and synthesis method, ie, spray pyrolysis 119 …”

Modulating the Electronic Structure of Ni/NiO Nanocomposite with High‐Valence Mo Doping for Energy‐Saving Hydrogen Production via Boosting Urea Oxidation Kinetics

“…[32,[34][35][36] However, few reports are only available for the synthesis of Ni/NiO and NiO nanoparticles via the pulsed laser ablation (PLA) technique. [37,38] According to our knowledge, no reports are available, specifically on the Mo-doped Ni/NiO nanoparticles fabricated using the PLA-assisted technique and their UOR performances. This motivated us to synthesize a Mo-doped Ni/NiO nanocomposite using an advanced PLAL technique and examine its electrocatalytic activity for UOR performance.…”

Enhancing the performance of Ni nanoparticle modified carbon felt towards glycerol electrooxidation: impact of organic additive

“…Nickel-based catalysts have been reported previously as excellent catalysts for several applications, especially in electrocatalysis such as water splitting, 8–15 fuel cells, 16–19 oxidation of many organic molecules (methanol, ethanol, glucose, urea, and glycerol). 20–37 This is attributed to its high stability in alkaline medium, low cost, high electro-catalytic activity, good electrical conductivity, and ease of active phase formation.…”

“…Remarkably, glycerol can be used to assist the anodic reaction in the water electrolysis process which is thermodynamically more favored than the oxygen evolution reaction to save the input energy. [3][4][5][6][7] Nickel-based catalysts have been reported previously as excellent catalysts for several applications, especially in electrocatalysis such as water splitting, [8][9][10][11][12][13][14][15] fuel cells, [16][17][18][19] oxidation of many organic molecules (methanol, ethanol, glucose, urea, and glycerol). [20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][35][36][37] This is attributed to its high stability in alkaline medium, low cost, high electro-catalytic activity, good electrical conductivity, and ease of active phase formation.…”
