“…These significant changes showed that the inserted layers formed by trimesic acid increased the rate of electrolyte diffusion across the surfaces and between the layers. In addition, since the cavitation effect caused by the bursting bubbles could cause serious damage to the nanostructure 35 , 36 , the evolution of bubbles on the electrode surface could impact the structural stability 37 . Digital photographs of O 2 release from different electrodes were captured during galvanostatic scans at 200 mA cm −2 .…”

Layered double hydroxides are promising candidates for the electrocatalytic oxygen evolution reaction. Unfortunately, their catalytic kinetics and long-term stabilities are far from satisfactory compared to those of rare metals. Here, we investigate the durability of nickel-iron layered double hydroxides and show that ablation of the lamellar structure due to metal dissolution is the cause of the decreased stability. Inspired by the amino acid residues in photosystem II, we report a strategy using trimesic acid anchors to prepare the subsize nickel-iron layered double hydroxides with kinetics, activity and stability superior to those of commercial catalysts. Fundamental investigations through operando spectroscopy and theoretical calculations reveal that the superaerophobic surface facilitates prompt release of the generated O2 bubbles, and protects the structure of the catalyst. Coupling between the metals and coordinated carboxylates via C‒O‒Fe bonding prevents dissolution of the metal species, which stabilizes the electronic structure by static coordination. In addition, the uncoordinated carboxylates formed by dynamic evolution during oxygen evolution reaction serve as proton ferries to accelerate the oxygen evolution reaction kinetics. This work offers a promising way to achieve breakthroughs in oxygen evolution reaction stability and dynamic performance by introducing functional ligands with static and dynamic compatibilities.

“…Typically, Chen et al developed superhydrophilic porous Co x P nanoarrays and disclosed that NF@Co x P-300 with the best superhydrophilicity and a pronouncedly increased ion transfer rate is beneficial for achieving remarkable HER performance. [77] In addition, Yu et al constructed Ni 2 P nanoarrays with superanaerobic surface features, which can effectively release the H 2 generated on the catalyst surface, thus achieving a stable and efficient HER electrocatalytic process at ultrahigh current densities. [78] Altogether, the adjustment of the surface wetting state is also responsible for the design of efficient TMP-based HER catalysts.…”

Developing efficient and inexpensive electrocatalysts for the hydrogen evolution reaction (HER) is critical to the commercial viability of electrochemical clean energy technologies. Transition metal phosphides (TMPs), with the merits of abundant reserves, unique structure, tunable composition, and high electronic conductivity, are recognized as attractive HER catalytic materials. Nevertheless, the HER electrocatalytic activity of TMPs is still limited by various thorough issues and inherent performance bottlenecks. In this review, these issues are carefully sorted, and the corresponding reasonable explanations and solutions are elucidated on the basis of the HER catalytic activity origins of TMPs. Subsequently, highly targeted multiscale strategies to improve the HER performance of TMPs are comprehensively presented. Additionally, critical scientific issues for constructing high‐efficiency TMP‐based electrocatalysts are proposed. Finally, the HER reaction process, catalytic mechanism research, TMP‐based catalyst construction, and their application expansion are mentioned as challenges and future directions for this research field. Expectedly, this review offers professional and targeted guidelines for the rational design and practical application of TMP‐based HER catalysts.
