“…[3][4][5][6][7] Layered double hydroxides (LDHs) of these transition metals have even surpassed the most active and stable IrO 2 and RuO 2 catalysts, largely due to their higher surface areas, but in turn suffer from poor conductivity. [8,9] In addition to these, compounds of transition metals in the form of phosphides, [10,11] sulfides, [12,13] borides, [14,15] selenides, [16,17] nitrides, [18,19] and carbides [20,21] have emerged as promising low-cost alternatives. In majority of the cases, these compounds are proposed to act as pre-catalysts that transform into reactive oxy-hydroxy (*OOH) species on the surface during OER, while still providing conducting pathways through the core.…”

New oxygen evolution reaction (OER) electrocatalysts based on low‐cost elements, which set new benchmark levels of activity, are vital if water electrolysis is to be applied on a global scale. Herein, a low‐cost bimetallic phospho‐boride catalyst was developed that showed outstanding OER activity of approximately 195 mV to achieve 10 mA cm−2 in alkaline water electrolysis, with a minimal catalyst loading of 0.3 mg cm−2. The contrasting electron transfer property of the metal borides and phosphides when combined in phospho‐boride modulated the electron density of the Co atom, yielding highly active CoOOH species at lower potentials. The addition of Mo at low levels further enhanced the activity by increasing the surface area and by formation of nano‐crystalline domains. The combined contributions from each of the components resulted in a new benchmark mass activity of 666 A g−1 at 300 mV overpotential. This work presents a new avenue towards fabricating electrode materials with exceptional performances.

“…17,18 Interesting nanostructures resembling natural shapes can be obtained. For instance, using solvothermal or hydrothermal strategies, ower-, [19][20][21][22][23] leaf-, 24,25 coral- [26][27][28][29][30] and seaurchin-like nanostructures have been reported recently, 31,32 demonstrating much enhanced performances in different applications. However, the biomimetic appearance of these patterns during the synthesis, in many cases, is not based on predictive mechanisms.…”

“…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.
