“…To pursue a higher cost efficiency, various non‐noble metal‐based electrocatalysts have been widely explored as promising alternative catalysts. In recent years, MOFs derivatives have been extensively applied in electrochemical reactions due to their abundant defects, diverse structures, and outstanding conversion efficiency 175–177 . For example, the Gan group proposed a surface engineering strategy to fabricate MOF‐derived hierarchical nickel‐copper http://nitride http://electrode with Ni and oxygen vacancies for achieving HER activity 178 .…”

The efficient electrocatalysis plays the key role in the development of electrochemical energy conversion technologies to alleviate energy crisis. Given their multiple active sites and large specific surface areas as electrocatalysts, metalorganic frameworks (MOFs) and their derivatives have attracted considerable interests in recent years. Specially, exploring the roles of the enhanced active sites in MOFs and their derivatives is significant for understanding and developing new effective electrocatalysts. Recently, the vital role of vacancies has been proven to promote electrocatalytic processes (such as H 2 or O 2 evolution reactions, O 2 reduction reactions, and N 2 reduction reactions). In order to in-depth exploring the effect of vacancies in electrocatalysts, the vacancies classification, synthetic strategy, and the recent development of various vacancies in MOFs and their derivatives for electrocatalysis are reviewed. Also, the perspectives on the challenges and opportunities of vacancies in MOFs and their derivatives for electrocatalysis are presented.

“…The requirements for MOFs to display electrocatalytic activity is to possess three electrochemical factors, i.e., onset potential, current density, and redox-active metal sites. MOF-derived electrocatalysts for HER have been extensively studied, such as a bimetallic NiMo-MOF composite with current density of 10 mA·cm −2 at low overpotential of 80 mV and Tafel slope of 98.9 mV·dec −1 , whose enhanced HER activity is due to the structural merits of MOF and the synergy between the MOF and the Ni/Mo metal atoms [ 195 , 196 ]. A cobalt phosphide 2D-MOF nanosheet showed excellent electrocatalytic performance for water splitting, i.e., HER and OER, in acidic and alkaline media with Tafel slopes of 59 and 64 mV·dec −1 and a current density of 10 mA·cm −2 at the overpotentials of 140 and 292 mV, respectively, which are comparable to those of commercial noble-metal catalysts [ 197 ].…”

Metal-organic frameworks represent a porous class of materials that are build up from metal ions or oligonuclear metallic complexes and organic ligands. They can be considered as sub-class of coordination polymers and can be extended into one-dimension, two-dimensions, and three-dimensions. Depending on the size of the pores, MOFs are divided into nanoporous, mesoporous, and macroporous items. The latter two are usually amorphous. MOFs display high porosity, a large specific surface area, and high thermal stability due to the presence of coordination bonds. The pores can incorporate neutral molecules, such as solvent molecules, anions, and cations, depending on the overall charge of the MOF, gas molecules, and biomolecules. The structural diversity of the framework and the multifunctionality of the pores render this class of materials as candidates for a plethora of environmental and biomedical applications and also as catalysts, sensors, piezo/ferroelectric, thermoelectric, and magnetic materials. In the present review, the synthetic methods reported in the literature for preparing MOFs and their derived materials, and their potential applications in environment, energy, and biomedicine are discussed.

“…Overview of general wisdom on supported catalysts and current knowledge on electrocatalytic HER is summarized in References [41][42][43]. Several fresh reviews deal with more specific catalyst and/or support materials, such as References [44][45][46] for carbon-based supports, References [47,48] for metal-organic frameworks, Reference [49] for 1D and 2D noble metals, and other specific materials in References [50][51][52]. A recent overview of heterostructured HER electrocatalysts can be found in Reference [53].…”

Hydrogen Evolution Reaction-From Single Crystal to Single Atom Catalysts

Hydrogen evolution reaction (HER) is one of the most important reactions in electrochemistry. This is not only because it is the simplest way to produce high purity hydrogen and the fact that it is the side reaction in many other technologies. HER actually shaped current electrochemistry because it was in focus of active research for so many years (and it still is). The number of catalysts investigated for HER is immense, and it is not possible to overview them all. In fact, it seems that the complexity of the field overcomes the complexity of HER. The aim of this review is to point out some of the latest developments in HER catalysis, current directions and some of the missing links between a single crystal, nanosized supported catalysts and recently emerging, single-atom catalysts for HER.
