Recent advances in metal/covalent organic frameworks based materials: Their synthesis, structure design and potential applications for hydrogen production

Enhanced thermal and porous properties of double-decker-shaped polyhedral silsesquioxane-bismaleimide (DDSQ-BMI) nanocomposites for high-performance CO2 storage and supercapacitors

“…[11][12][13][14][15] The various POPs are produced by synthetic approaches that incorporate conjugated microporous polymers (CMP), covalent organic frameworks (COF), covalent triazine frameworks, and hyper-crosslinked polymers (HCP), and they are constructed using imine, azine, imide and triazine linkages. [16][17][18][19][20] The conventional approach for synthesizing HCPs involves Friedel-Crafts alkylation, albeit with the associated drawbacks of environmentally unfriendly generation of harmful byproducts and use of volatile solvents. 21,22 As a result, an alternative approach for HCP synthesis based on free radical polymer-ization using bismaleimide (BMI) derivatives has been investigated with green and atom-economical procedures.…”

Single-Atom Catalysts on Covalent Organic Frameworks for Energy Applications

“…1,19 To disperse metals atomically homogeneously and achieve the best possible efficiency from such an arrangement, one strategy is to confine and stabilize the metal atoms in substrate skeletons with atomic-scale precision. For these purposes, substrates have been widely investigated, including metal oxides, 1,13 graphene, 20,21 porous polymers, 22,23 metal−organic frameworks (MOFs), 24,25 covalent organic frameworks (COFs), 19,26 etc.…”

“…Therefore, the main challenges in developing effective SACs are (1) achieving high metal loadings while keeping the stability of the SACs and (2) creating more manageable synthesis pathways for SACs at low costs. , To disperse metals atomically homogeneously and achieve the best possible efficiency from such an arrangement, one strategy is to confine and stabilize the metal atoms in substrate skeletons with atomic-scale precision. For these purposes, substrates have been widely investigated, including metal oxides, , graphene, , porous polymers, , metal–organic frameworks (MOFs), , covalent organic frameworks (COFs), , etc.…”

Design and Synthesis of Bisulfone-Linked Two-Dimensional Conjugated Microporous Polymers for CO2 Adsorption and Energy Storage

“…The pursuit of green environmental protection without affecting the life experience of most consumers, or how to ensure the supply and demand of energy while improving economic effects, is a heavy part of technology today. An increasingly well-known energy storage device to deal with this situation is the supercapacitor (SC), which has been studied since the 19th century [ 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 ]. SCs were developed for the same purpose as secondary batteries and conventional capacitors.…”
