Investigating the relationship between substituent groups of nanoporous organic polymers and adsorption capacities for SO2, NH3, CO2, I2 is a significant challenge. In this study, four polyaminal networks (NPANs) with methyl or phenyl were prepared, they demonstrated high I2. The NPANs, which referred to as NPAN-1, NPAN-2, NPAN-3, NPAN-4, fabricated via one-pot polycondensation method by using inexpensive p-phthalaldehyde (p-PDA) m-phthalaldehyde (m-PDA) 6-methyl-1,3,5-triazine-2,4-diamine (MTDA) 2,4-diamino-6-phenyl-1,3,5-triazine (DAPT). NPANs had dense aminal-rich structure stable nanoporosity, contributed their SO2/CO2 selectivities. Notably, SO2 capacities, NH3 CO2 NPAN-1 electron-donating groups, higher than those NPAN-2 electron-withdrawing groups. This result indicated that introduction into an NPAN enhanced electron density nitrogen atoms in network, leading increases study offers important insights design synthesis adjustable properties tackle environmental industrial challenges.

Covalent triazine frameworks (CTFs) drive innovative advances in rechargeable metal-ion batteries: a review

Energy Materials, Год журнала: 2024, Номер 4(6)

In the field of energy storage technology, organic electrodes, separators, and electrolytes have unique advantages over inorganic materials, such as low cost, environmental friendliness, a wide range applications. Due to organics light elements, abundant reserves, recyclability, they become favorable candidate materials for solving problems caused by fossil crisis. recent years, high-performance branch covalent frameworks, triazine structures (CTFs) attracted great interest due their applications in electrochemical storage. CTFs gradually excellent metal-ion batteries large specific surface area, nitrogen richness, customizable structural features, electron donor-acceptor/conductive parts. However, relatively poor conductivity ring main structure harsh polycondensation conditions limit its commercial application. To overcome these challenges, many effective strategies emerged terms optimization, functional construction, triazine-based composites. This review summarizes detail synthesis methods cathodes, electrolytes, separators past decade. It is found that CTFs, large-scale performance regulation reached bottleneck. hoped systematic summary this will provide strategic screening prospects further expansion research next-generation batteries.
