2024年6月5日 · To collect comprehensive insights into the early stages of COF formation, we chose the 2D imine COF termed TA-TAPB (TA, terephthalaldehyde; TAPB, 1,3,5-tris (4-aminophenyl)benzene) as a...

本文通过先进的表征技术，揭示了TAPB-DMPDA COF的双孔AA'堆叠结构，这一结构在孔径分布和电荷分布上与传统模型有显著差异，对COFs在分离和催化应用中的性能有重要影响。

2023年4月4日 · TAPB-PDA COF can be made from the condensation reaction between TAPB and PDA and is a well-studied COF with applications in modern separation and filtration technologies.

2023年12月19日 · As a result, three distinct COFs were successfully synthesized with CNFs, yielding nanocomposites referred to as CNF@TFB-DB COF, CNF@TFB-TAPB COF, and CNF@TFB-ETTA COF. The purified CNF@COF products exhibited a characteristic nanofiber structure, with the nanofiber thickness ranging from 44 to 67 nm as observed from the TEM images ( Figures 4 b ...

2021年12月1日 · Mechanical testing for fracture strength and Young’s modulus of COF TAPB-DHTA films revealed values of 0.75 ± 0.34 GPa and 10.38 ± 3.42 GPa, respectively. These values show that the COF TAPB-DHTA films has a comparable mechanical strength with Kevlar thin films, as well as nylon- and epoxy-based polymeric materials ( Fig. 6 b).

2023年9月6日 · We began by synthesizing monodisperse, submicrometer-sized colloidal spherical particles of the imine-linked TAPB-BTCA-COF. Both 1,3,5-tris(4-aminophenyl)benzene (TAPB) (0.04 mmol) and benzene-1,3,5-tricarbaldehyde (BTCA) (0.04 mmol) were first dissolved in 5 mL of acetonitrile containing acetic acid (AcOH) (12 M).

2024年12月30日 · The yield of photoreduction of CO 2 to CO by the TAPB-COFZ-30 heterojunction photocatalyst reached 2895.94 μmol g −1 with high selectivity (95.75%). This study provides a feasible strategy for constructing highly active core–shell composite photocatalysts to optimize CO 2 reduction.

室温合成cof材料rt-cof-1，具备优异的n2和co2吸附性能，通过lcw和喷墨打印技术实现在刚性和柔性基底上的微米级图案化，开启材料科学新篇章。 CHEMSOON-专业室温大量合成各类COF材料

2022年1月17日 · The separation performances of TAPB-BTCA-MCOF for the gas mixture CO 2 /CH 4 or CO 2 /N 2 are close to the upper bound limits. Therefore, we believe that this novel processing method, once optimized, opens new avenues to produce large-scale COF-membranes with controlled size and thickness for different applications, going from nanofiltration to ...

In this study, we proposed a Z-scheme heterojunction WO /covalent organic framework (Tp–TAPB) that can accelerate the separation and charge transfer at the interface and retain the strong oxidative and reductive ability of WO and Tp–TAPB.
