Recent Development of Zeolitic Imidazolate Frameworks (ZIFs) Derived Porous Carbon Based Materials as Electrocatalysts

Abstract

Development of effective, stable, and economic electrocatalysts is critical for further implementation of fuel cells, water electrolysis, and metal–air batteries in clean energy conversion technologies. As a subfamily of metal–organic frameworks (MOFs), zeolitic imidazolate frameworks (ZIFs) possess the characteristics of both MOFs and zeolites, showing highly porous structures, large surface area, and open catalytic active sites. This review presents materials design strategies for constructing improved electrocatalysts based on ZIF precursors/templates, with special emphasis on the varieties of derivatives, controllable building of active sites, the construction of macroscopic structure, and the favored electrocatalytic reactions based on these materials. These ZIF‐derived N‐doped carbon‐based composites or compounds have exhibited remarkable activity and stability for a broad electrocatalysis application, displaying great potential to replace noble‐metal‐based catalysts. The challenges and perspectives regarding ZIF‐derived electrocatalysts are also discussed for better development of ZIF‐derived electrocatalysts.

Engineering Ultrathin MoS2 Nanosheets on CoxP/Nitrogen‐Doped Carbon Nanocubes for Efficient Hydrogen Evolution

“…ZIFs are employed as precursors/self-sacrificing templates because of their high density of cobalt and nitrogen species in the framework, large surface area, high stability, and regular morphology. [14] Then, the obtained Co/NC nanocubes are in situ converted to Co x P/NC via a solid-phase phosphating treatment. Subsequently, MoS 2 nanosheets are uniformly engineered on Co x P/NC nanocubes by a hydrothermal approach.…”

Carbon-based derivatives from metal-organic frameworks as cathode hosts for Li–S batteries

“…A large number of studies indicate that ZIF-8 has good thermal stability and high porosity, and ZIF-67 has tunable pore structure and catalytic activity [88,[123][124][125][126] . According to previous reports, both high N content and highly graphitized structure are difficult to be realized at the same time because the N content largely decreases during the graphitization of carbon at high temperature [127] .…”

Electrochemical Energy Conversion and Storage with Zeolitic Imidazolate Framework Derived Materials: A Perspective

“…Due to the presence of a large number of cobalt cations intrinsically mono‐dispersed in ZIF‐67, numerous cobalt based materials such as mono or bi‐metallic oxides/hydroxides/phosphides/selenides/sulfides with hollow, porous nanostructures can be fabricated directly from ZIF‐67 by using solvothermal and chemical vapor deposition (CVD) protocols. In addition, ZIF‐67 offers the ability to design plenty of bimetallic electrocatalysts or composites with nickel, iron, molybdenum, etc., from ZIF‐67 hybrids . These target structures are highly favorable for achieving enhanced electrochemical performance.…”
