“…Precursor design and morphology control are common strategies for enhancing the catalytic activities of carbon materials (Zhao et al, 2021). Zeolitic imidazolate framework (ZIF-8) has long been regarded as an ideal carrier owing to its high conductivity, excellent thermal stability, and porous structure (Son et al, 2019). Nevertheless, the carbon matrix obtained by carbonizing ZIF-8 exhibits an unsatisfactory microstructure and low conductivity in acidic electrolytes (Li et al, 2020), which limits the development of ZIF-8 as a metal-free catalyst.…”

“…Sumin et al [89] prepared nitrogen and sulfur co-doped porous carbon (NSDPC) electrocatalyst for ORR by impregnation and carbonization using ZIF-8 as a template. The effect of the carbonization temperature and doping densities (controlled by varying the weight ratio between ZIF-8 and thiourea) on the activity of the catalyst was studied.…”

Supercapacitors (SCs) are recognized by high power densities and significantly higher cyclic stability compared to batteries. However, the energy density in SCs should be improved for better applications and commercialization. This could be achieved by developing materials characterized by such porous structures as metal-organic frameworks (MOFs) and metal chalcogenides in the electrodes’ materials. Herein, the recent advances in MOF derived from metal sulfides and selenides as electrode materials for SCs are reviewed and discussed. Strategies such as adopting core-shell structures, carbon-coating, and doping, which are used to promote the electrochemical performances of these MOF-based materials, are presented. Additionally, the progress in developing S-doped MOF-derived catalysts for the oxidation-reduction reaction (ORR) in the cathode of fuel cells is also reviewed. In addition, the challenges and future research trends are summarized in this minireview.

“…Metal–organic frameworks (MOFs) are fabricated by linking inorganic and organic units by weak bonds (reticular synthesis), which form porous materials with a periodic network structure through self-assembly under the actions of coordination bonds [ 9 , 10 , 11 , 12 ]. Due to the simplicity and low cost of preparing MOFs, they have considerable potential for future applications, including gas storage [ 10 , 11 , 12 , 13 , 14 , 15 , 16 ], drug delivery [ 17 , 18 , 19 , 20 , 21 ], molecular separation [ 22 , 23 , 24 , 25 ], chemical catalysis [ 26 , 27 , 28 , 29 , 30 , 31 ], and energy storage [ 32 , 33 , 34 , 35 , 36 , 37 , 38 , 39 , 40 , 41 , 42 , 43 , 44 ]. According to Tai et al’s work, the as-synthesized ZIF-8 calcined at 800 °C under an N 2 atmosphere and converted to N-doped carbon can be used as an anode for LIBs.…”

“…Son et al synthesized ZIF-8 under N 2 flow and impregnated in thiourea and ethanol solution; the material was then calcined under N 2 at 900 °C. Finally, they synthesized N, S-doped nanocarbon, which exhibited high electrochemical performance [ 36 ]. Tang et al proposed ZIF-8@ZIF-67 core-shell nanostructures by using a seed-mediated growth technique [ 37 ].…”

Through high-temperature sintering and carbonization, two Co/ZnO nitrogen-doped porous carbon (NC) composites derived from ZIF-8 and ZIF-67 were manufactured for use as anodes for Li ion batteries: composite-type Co/ZnO-NC and core-shell-type Co@ZnO-NC. X-ray diffraction analysis, scanning electron microscopy, and the Brunauer–Emmett–Teller (BET) method were performed to identify the pore distribution and surface morphology of these composites. The findings of the BET method indicated that the specific surface area of Co/ZnO-NC was 350 m2/g, which was twice that of Co@ZnO-NC. Electrochemical measurements revealed that Co@ZnO-NC and Co/ZnO-NC had specific capacities of over 400 mAh g−1 at a current density 0.2 A g−1 after 50 cycles. After 100 cycles, Co/ZnO-NC exhibited a reversible capacity of 411 mAh g−1 at a current density of 0.2 A g−1 and Co@ZnO-NC had a reversible capacity of 246 mAh g−1 at a current density of 0.2 A g−1. The results indicated that Co/ZnO-NC exhibited superior electrochemical performance to Co@ZnO-NC as a potential anode for use in Li ion batteries.
