“…Considering the electrocatalysis of the gas‐involving reactions, it is desirable to find electrocatalysts with the abilities of fast electron/mass transport and abundant triphase regions for interface reactions 42–44 . In the past few decades, a large number of nanomaterials with superior electrocatalytic activity have been designed for electrochemical reactions, 45–50 where, metal‐organic frameworks (MOFs), a novel class of nanoporous materials, have acted as promising material platform with versatile applications such as catalysts, adsorbents of gas storage and separation, batteries, substrates for drug delivery and biosensors 51–66 . Owing to their intrinsic aesthetic, such as large surface area, isolated active site, open crystalline structure, and exceptional porosity, MOFs have been considered as heterogeneous electrochemical catalysts for various electrocatalysis reactions 67–73 .…”

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.

“…SCs are promising energy storage devices, and have attracted extensive attention due to their rapid charge and discharge rates, high power density, and long life [3]. Two main mechanisms are responsible for storing energy in supercapacitors: the electrical double layer capacitance (EDLC) and the pseudocapacitance [4][5][6].…”

Cheap and efficient carbon electrodes (CEs) for energy storage systems (ESS) such as supercapacitors (SCs) and batteries are an increasing priority issue, among other things, due to a globally increasing share of intermittent electricity production (solar and wind) and electrification of transport. The increasing consumption of portable and non-portable electronic devices justifies research that enables environmentally and economically sustainable production (materials, processing techniques, and product design) of products with a high electrochemical performance at an acceptable cost. Among all the currently explored CEs materials, biomass-based activated carbons (AC) present enormous potential due to their availability and low-cost, easy processing methods, physicochemical stability, and methods for self-doping. Nitrogen doping methods in CEs for SCs have been demonstrated to enhance its conductivities, surface wettability, and induced pseudocapacitance effect, thereby delivering improved energy/power densities with versatile properties. Herein, a short review is presented, focusing on the different types of natural carbon sources for preparing CEs towards the fabrication of SCs with high electrochemical performance. The influences of ACs’ pore characteristics (micro and mesoporosity) and nitrogen doping on the overall electrochemical performance (EP) are addressed.

“…Meanwhile, MOF-derived materials can offer a rich metal and carbon source for large redox activity and high electrical conductivity. [5] By virtue of the distinct advantages, a large number of MOFs and their derivatives have been developed for energy conversion and storage applications, and some review articles have summarized their usage, especially the MOF-derived carbon and metal oxide materials with a specific architecture in supercapacitors. [6] In this review, we will comprehensively summarize the recent progress of pristine MOFs, MOF composites, and MOF-derived functional materials for supercapacitor electrode application.…”

Metal-organic frameworks (MOFs) are deemed an attractive type of active material during electrochemical reaction processes because of their unique compositional and structural superiority, as well as the dual role as both templates and precursors to derive a large variety of functional materials for energy conversation and storage. Herein, reviewing the recent advances of MOFs and their derived functional materials as electrode materials in supercapacitors, which are classified into pristine MOFs, MOF composites, and MOF-derived functional materials, is focused on. Their synthetic routes and modification strategies are summarized and the relationship between the diversity of the architectures and compositions of MOF-based materials and their electrochemical performance is discussed. In addition, the challenges and opportunities on future research and extensive applications of MOFs and their derived functional materials are offered.
