“…Then by the Heyrovsky reaction, the molecular hydrogen is formed by the combination of electron, proton, and adsorbed hydrogen. The final step is the Tafel reaction in which molecular hydrogen is formed by recombination of two adsorbed hydrogen atoms, as explained in eqs –) H 2 normalO + normalM + e − ⇋ SH ads + OH − 0.25em normalVolmer 0.25em normalstep SH ads + H 2 normalO + e − ⇋ normalS + H 2 + OH − 0.25em normalHeyrovsky 0.25em normalstep 2 SH ads ⇋ 2 S + H 2 0.25em normalTafel 0.25em normalstep where SH ads represents the chemically adsorbed H atoms on catalyst active sites (S).…”

Nickel ferrites (NiFe 2 O 4 ) having rich redox chemistry are regarded as proficient electrocatalysts for sustainable and renewable energy applications. However, its entire potential as an electrode material is limited by its weak structural characteristics and inadequate charge transport qualities. This work reports a series of zinc-substituted inverse spinel ferrites (Zn x Ni 1−x Fe 2 O 4 ) synthesized by a simple and environmentally benign hydrothermal method as electrocatalysts for overall water splitting. The surface morphology, structural elements, and electronic properties of resultant materials are significantly changed by Zn inclusion. Among different compositions, the ferrite sample Zn 0.5 Ni 0.5 Fe 2 O 4 showed outstanding water splitting performances, with a current density of 100 mA•cm −2 for OER and HER at the cost of 290 mV and 311 mV overpotentials, respectively. The electrode demonstrated lower Tafel slopes of 56 and 46 mV•dec −1 for HER and OER with a high turnover frequency (TOF) and exchange current density (j 0 ). Significantly, this electrode demanded a cell voltage of 1.48 V in a two-electrode electrolyzer to deliver 10 mA•cm −2 and showed good stability for 24 h. This is attributed to the efficient charge transport properties of the Zn-incorporated NiFe 2 O 4 with high electrical conductivity and charge transfer characteristics. Overall, the findings highlighted the potential of Zn-incorporated NiFe 2 O 4 as a promising electrocatalyst for renewable hydrogen production.

“…Through an expansive and diverse range of synthetic methodologies, a vast and diverse library of shapes, sizes and morphologies have been explored as catalysts for the HER. Various reviews have been published on nanostructuring HER catalysts, including reviews focused on nanostructured phosphides, nitrides, nickel-based electrocatalysts, , molybdenum disulfide, and core–shell morphologies . More broad reviews on nanostructured HER catalysts have also been published. − At the crux of nanostructuring catalysts is the notion that by increasing the catalyst surface area, the geometric density of active sites will also be increased.…”

The quest to identify precious metal free hydrogen evolution reaction catalysts has received unprecedented attention in the past decade. In this Review, we focus our attention to recent developments in precious metal free hydrogen evolution reactions in acidic and alkaline electrolyte owing to their relevance to commercial and near-commercial low-temperature electrolyzers. We provide a detailed review and critical analysis of catalyst activity and stability performance measurements and metrics commonly deployed in the literature, as well as review best practices for experimental measurements (both in half-cell three-electrode configurations and in two-electrode device testing). In particular, we discuss the transition from laboratory-scale hydrogen evolution reaction (HER) catalyst measurements to those in single cells, which is a critical aspect crucial for scaling up from laboratory to industrial settings but often overlooked. Furthermore, we review the numerous catalyst design strategies deployed across the precious metal free HER literature. Subsequently, we showcase some of the most commonly investigated families of precious metal free HER catalysts; molybdenum disulfide-based, transition metal phosphides, and transition metal carbides for acidic electrolyte; nickel molybdenum and transition metal phosphides for alkaline. This includes a comprehensive analysis comparing the HER activity between several families of materials highlighting the recent stagnation with regards to enhancing the intrinsic activity of precious metal free hydrogen evolution reaction catalysts. Finally, we summarize future directions and provide recommendations for the field in this area of electrocatalysis.

The performance of a water electrolyser (WE) depends on several aspects, many of which are located in the powerhouse of the cell, namely, the membrane electrode assembly (MEA). The anion exchange membrane WE (AEMWE) is a promising technology; however, both activity and stability must be further developed to surpass the current dominant WE technologies. Herein, we review aspects related to MEA development for anion exchange membrane water electrolysers, covering materials and techniques from the perspective of stability and activity. The gas diffusion layer (GDL) and the microporous layer (MPL) are often combined into a single MEA component, which places great importance on its composition. This composite layer has the greatest impact of any single component on cell performance, as the physical architecture of the GDL/MPL influences the overpotential related to activation, ohmic, and mass transport. The purpose of this review is to serve as an executive summary of the literature related to MEAs for AEMWEs for researchers and industry professionals who seek to further the state of the art.
