Nitrogen doped NiFe layered double hydroxide/reduced graphene oxide mesoporous nanosphere as an effective bifunctional electrocatalyst for oxygen reduction and evolution reactions

A NiFe layered double hydroxide-decorated N-doped entangled-graphene framework: a robust water oxidation electrocatalyst

“…15,16 Among various cost-effective conducting supports, carbon-based materials with electrochemically favourable characteristics, i.e., high electronic conductivity and surface area, have emerged as universal choices in the electrocatalysis eld. 15,16 For instance, in a recent report, Zhan et al 17 achieved improved activity and stability by anchoring the OER-active NiFe layered double hydroxides over nitrogen-doped graphene. Similarly, Chandrasekaran et al 18 also reported improved OER performance by anchoring NiFe layer double hydroxides over reduced graphene oxide.…”

A Review on Membranes and Catalysts for Anion Exchange Membrane Water Electrolysis Single Cells

“…However, the performance of such AEMs should be confirmed in a water electrolysis configuration since the cell performance is highly dependent on the cell operating conditions. OER [52][53][54][55][56][57][58][59][60][61][62] and hydrogen evolution reaction (HER) [56,57,[63][64][65][66][67][68][69][70][71][72][73][74] catalysts have also been developed actively for alkaline water electrolysis with the aim of achieving high catalytic activity and chemical stability under alkaline conditions. These developments have focused predominantly on controlling the crystalline structure and morphology of the catalysts and testing various transition metals or their oxides [75].…”

Strongly Coupled Interface Structure in CoFe/Co3O4 Nanohybrids as Efficient Oxygen Evolution Reaction Catalysts

“…The two peaks located at 780.6 and 796.3 eV were assigned to Co 3+ , and the two peaks located at 782.2 and 797.9 eV were attributed to Co 2+ , whereas the other two peaks located at 787.5 and 803.7 eV were ascribed to corresponding shakeup satellites . The Fe 2p spectrum shown in Figure e could be deconvoluted into two prominent peaks, which appeared at 712.3 and 725.2 eV, attributed to Fe 2p 3/2 and Fe 2p 1/2 , respectively, along with two satellite peaks at 718.8 and 734.5 eV, indicating the Fe 3+ oxidation state . For the O 1s spectrum, three kinds of oxygen species were observed in Figure f: the peaks located at 530.1, 531.2, and 532.3 eV were attributed to O−M−O bonds, OH bonds, and oxygen vacancies, respectively .…”
