Study on Ni–Fe–C cathode for hydrogen evolution from seawater electrolysis

Novel Fe–Ni-Graphene composite electrode for hydrogen production

“…As shown in Fig. 5, the peaks at 2q values of 43.4 , 50.6 and 74.5 correspond to characteristic peaks of taenite ironenickel, which could be assigned to (111), (200) and (220) reflection, respectively, of FCC ironenickel [26,37]. At 60 mA cm À2 there was a shift from FCC to BCC phase with appearance of reflection at (110) preferred orientation.…”

“…Materials like TiO 2 , RuO, MoO 2 , tungsten carbide and carbon nanopowder are used in combination with transition metals to enhance their electrocatalytic behaviour and stability [29e35]. Recently, interesting findings on the effect of embedded carbon content in FeeNi electrodes for HER in seawater were reported [36,37]. The presence of carbon content was found to be beneficial in enhancing the electrocatalytic property of the material.…”

Electrocatalysts for Water Electrolysis

“…Ni-based alloys are widely used cathodes for the electrolysis of alkaline waters due to the relatively high catalytic activity of Ni, and the synergism in the catalytic behavior of various components in the metal alloy. Alloys such as NiCo [35][36][37][38][39][40][41], NiFe [42][43][44][45][46], NiMo [43,[47][48][49][50][51][52][53][54][55][56][57][58][59], NiW [47,60,61], NiCu [62,63], NiAl [6,[64][65][66][67][68], NiZn [69][70][71][72][73], NiMoFe [56,[74][75][76][77] were used by means of different methods. Materials based on nickel and molybdenum attract ever growing attention because of their activity for HER and sufficient corrosion resistance in...…”

Effect of current density on magnetic properties of electrodeposited Fe-Ni films prepared in a citric-acid-based-bath

“…It is well-known that the current density affects various properties of electrodeposited films and a high current density tends to reduce grain sizes of the films. [6][7][8][9][10] It is also well-known that reduction in a grain size improves soft magnetic properties for nanocrystalline soft magnetic materials due to the exchange softening effect.…”
