“…To further verify the qualification as the substitute of present catalyzer, we compared CoSe@NMC and commercial catalyst (IrO 2 and Pt/C) by LSV and ADTs. [ 46,47 ] For OER performances (in Figure a), CoSe@NMC possesses the same onset potential at 10 mA cm −2 (1.52 V) with IrO 2 but significantly higher current density than IrO 2 at the onset potential. The advantage was also demonstrated by Tafel slopes (in Figure 4b), as the lowest Tafel slope (66.1 mV dec −1 ) of CoSe@NMC confirming optimized kinetics.…”

“…For decades, numerous researches on highly efficient bifunctional oxygen electrocatalysts have been published. Table 1 summarizes recently studied catalysts with high bifunctional activities, which could be divided to noble metal‐based catalysts [ 68–74 ] , carbon‐based metal‐free catalysts, [ 75–80 ] and transition metal‐based catalysts (including metal/metal alloys [ 81–85 ] , oxides [ 86–88 ] , hydroxides [ 89–92 ] , chalcogenides [ 93–95 ] , phosphides [ 96–99 ] , nitrides [ 100–102 ] , carbides, [ 103–105 ] and MOFs [ 106,107 ] ). Especially, for metal chalcogenides, nitrides, and phosphides, they may be oxidized to the corresponding metal oxides/hydroxides in the oxidative environments of OER.…”

Designing an efficient air electrode is of great significance for the performance of rechargeable zinc (Zn)‐air batteries. However, the most widely used approach to fabricate an air electrode involves polymeric binders, which may increase the interface resistance and block electrocatalytic active sites, thus deteriorating the performance of the battery. Therefore, binder‐free air electrodes have attracted more and more research interests in recent years. This article provides a comprehensive overview of the latest advancements in designing and fabricating binder‐free air electrodes for electrically rechargeable Zn‐air batteries. Beginning with the fundamentals of Zn‐air batteries and recently reported bifunctional active catalysts, self‐supported air electrodes for liquid‐state and flexible solid‐state Zn‐air batteries are then discussed in detail. Finally, the conclusion and the challenges faced for binder‐free air electrodes in Zn‐air batteries are also highlighted.

“…Non‐metallic‐atom doping has also been utilized to enhance the OER efficiency of the electrospun nanomaterials‐based electrocatalsyts 143‐147 . For example, owing to the doping‐induced charge distribution, N, F, P ternary doped macro‐porous CNFs showed a good OER activity with a lower onset potential of 1.3 V without iR compensation 146 .…”

Nowdays, electrocatalytic water splitting has been regarded as one of the most efficient means to approach the urgent energy crisis and environmental issues. However, to speed up the electrocatalytic conversion efficiency of their half reactions including hydrogen evolution reaction (HER) and oxygen evolution reaction (OER), electrocatalysts are usually essential to reduce their kinetic energy barriers. Electrospun nanomaterials possess a unique one‐dimensional structure for outstanding electron and mass transportation, large specific surface area, and the possibilities of flexibility with the porous feature, which are good candidates as efficient electrocatalysts for water splitting. In this review, we focus on the recent research progress on the electrospun nanomaterials‐based electrocatalysts for HER, OER, and overall water splitting reaction. Specifically, the insights of the influence of the electronic modulation and interface engineering of these electrocatalysts on their electrocatalytic activities will be deeply discussed and highlighted. Furthermore, the challenges and development opportunities of the electrospun nanomaterials‐based electrocatalysts for water splitting are featured. Based on the achievements of the significantly enhanced performance from the electronic modulation and interface engineering of these electrocatalysts, full utilization of these materials for practical energy conversion is anticipated.
