There has been a direct correlation between the rate of industrial development and spread pollution on Earth, particularly in last century. The organic inorganic pollutants generated from activities have created serious risks to human life environment. concept sustainability emerged tackle environmental issues developing chemical-based industries. However, continued be discharged water resources, finding appropriate techniques for removal remedy wastewater is high demand. Chromium one high-risk heavy metals wastewaters that should removed via physical adsorption and/or transformed into less hazardous chemicals. Photocatalysis as sustainable process received considerable attention it utilizes sunlight irradiation Cr(VI) cost-effective process. Numerous photocatalytic systems developed up now, but metal–organic frameworks (MOFs) gained growing because their unique versatilities facile structural modulations. A variety MOF-based photocatalysts widely employed photoreduction Cr(VI). Here, we review recent progress design MOF summarize performance reactions.

Highly Crystalline Polyimide Covalent Organic Framework as Dual-Active-Center Cathode for High-Performance Lithium-Ion Batteries

Journal of the American Chemical Society, Journal Year: 2022, Volume and Issue: 144(51), P. 23534 - 23542

Polyimide covalent organic framework (PI-COF) materials that can realize intrinsic redox reactions by changing the charge state of their electroactive sites are considered as emerging electrode for rechargeable devices. However, highly crystalline PI-COFs with hierarchical porosity less reported due to rapid reaction between monomers and poor reversibility polyimidization reaction. Here, we developed a water-assistant synthetic strategy adjust rate polyimidization, PI-COF (COFTPDA-PMDA) kgm topology consisting dual active centers N,N,N′,N′-tetrakis(4-aminophenyl)-1,4-benzenediamine (TPDA) pyromellitic dianhydride (PMDA) ligands was successfully synthesized high crystallinity porosity. The COFTPDA-PMDA possesses micro-/mesoporous channels largest surface area (2669 m2/g) in PI-COFs, which promote Li+ ions bulky bis(trifluoromethanesulfonyl)imide (TFSI–) electrolyte sufficiently interact on COF skeleton increase specific capacity cathode materials. As material lithium-ion batteries, COFTPDA-PMDA@50%CNT integrated center carbon nanotubes via π–π interactions gave initial 233 mAh/g (0.5 A/g) maintains at 80 even current density 5.0 A/g after 1800 cycles.
