Recent Progress in Covalent Organic Frameworks for Cathode Materials

Polymers, Journal Year: 2024, Volume and Issue: 16(5), P. 687 - 687

Published: March 2, 2024

Covalent organic frameworks (COFs) are constructed from small molecules through reversible covalent bonds, and therefore considered a special type of polymer. Small divided into nodes connectors based on their roles in the COF’s structure. The connector generally forms bonds with node two reactive end groups. adjustment length facilitates pore size. Due to diversity COFs have formed large family since synthesis 2005. Among them, COF containing redox active groups such as –C=O–, –C=N–, –N=N– has received widespread attention field energy storage. ordered crystal structure ensures arrangement consistent size pores, which is conducive formation unobstructed ion channels, giving these high-rate performance long cycle life. voltage specific capacity jointly determine density cathode materials. For COFs’ materials, plateau sites’ VS metallic lithium mostly between 2 3 V, great room for improvement. However, there currently no feasible strategy this. Therefore, previous studies mainly improved theoretical materials by increasing number sites. We summarized progress research types recent years found that functional can be six subcategories. According different groups, also Here, we summarize structure, unit, surface area, capacity, range COFs.

Triphenylamine-Substituted Ni(II) Porphyrins for Urea Electro-oxidation

Inorganic Chemistry, Journal Year: 2024, Volume and Issue: unknown

Published: Oct. 23, 2024

Porphyrin-based molecular catalysts possess a typical aromatic macrocyclic structure regarding their metal centers and coordination frameworks, allowing for the development of promising electrocatalysts through precise selection porphyrin ligand. However, reports on metalloporphyrins as electrocatalytic urea oxidation reaction (UOR) remain scarce. With these considerations in mind, triphenylamine-Ni(II) (NiPor-TPA) was synthesized solvothermal approach from 5,10,15,20-tetrakis [4-(diphenylamino)phenyl]porphyrin nickel(II) acetate this work. Experimental results reveal that introduction Ni species can serve active sites activate efficiently, thus prepared deliver better activity than metal-free TPA. The NiPor-TPA electrode delivers lowest potential 1.34 V versus reversible hydrogen (RHE) at 10 mA cm
