Constructing electrospun spinel NiFe₂O₄nanofibers decorated with palladium ions as nanosheets heterostructure: boosting electrocatalytic activity of HER in alkaline water electrolysis

Abstract

Development of efficient electrocatalyst for water splitting process and understanding their fundamental catalytic mechanisms are highly essential to achieve high performance in energy conversion technologies. Herein, we have synthesised of...

Redox-active Sn(ii) to lead to SnFe2O4 spinel as a bi-functional water splitting catalyst

“…S10a, ESI; † LSV with graphite rod counter electrode). SnFe 2 O 4 /NF electrode under anodic scan showed a fair OER activity towards delivering j of 250 mA cm À2 only at 1.61 V (vs. RHE) and an overpotential of 263 mV at 10 mA cm À2 which are significantly lower than that observed for noble metal-based catalysts and cobalt, nickel, and copper ferrites reported earlier (Table S1, ESI †) 18,26,27 (Fig. 2b, Fig.…”

Biomimicry-inspired fish scale-like Ni3N/FeNi3N/NF superhydrophilic/superaerophobic nanoarrays displaying high electrocatalytic performance

“…This explains why the hierarchical structure will have enhanced the catalytic activity. Moreover, adjusting the electronic structures through heteroatom doping, [19][20][21][22][23] defect induction, [24][25][26][27] and heterostructure [28][29][30][31] have also been experimentally demonstrated to improve the catalytic activity of the catalyst. For instance, Wu et al 32 anchored porous Ni 2 P/NiCoP heterostructure nanoarrays with rich grain boundaries on NF substrate through hydrothermal acid etching and static gas-phase phosphating processes.…”

Boosting the Activity of the Oxygen Evolution Reaction through an Electrospun Nickel Manganese-Based Bimetallic Zeolite Imidazolate Framework Fibrous System in Alkaline Medium

“…To make these steps feasible both thermodynamically and kinetically, many electrocatalysts have been identified and studied. Among that, many transition metal-based nonprecious metal oxides, , hydroxides, , layered double hydroxides, , sulfides , and selenide materials are showing comparable and superior activity with noble metal catalysts.…”
