2021年3月15日 · In this work, a monomer-mediated in situ growth strategy was developed for the controllable construction of core-shell Co 3 O 4 @TAPB-DMTP−COF composite (TAPB, 1,3,5-tris(4-aminophenyl)benzene; DMTP, 2,5-dimethoxyterephaldehyde; COF, covalent organic framework), which exhibits uniform size, high surface area, outstanding thermochemical ...

2021年6月1日 · With this background in mind, we propose to synthesize a PANI coated TAPB-DMTP-COF (TAPB-DMTP-COF@PANI) composite via a facile chemical oxidative polymerization method. Characterizations were made by X-ray diffraction patterns (XRD), fourier transform infrared spectra (FTIR), X-ray photoelectron spectroscopy (XPS), transmission electron ...

在这项工作中，该论文合成了一系列具有不同侧链长度的tapb-pda-r cof，通过xrd和结构细化生成模型发现侧链长度为1个和5-9个碳时cof具有最高的结晶度且显著高于2-4个碳。

2021年12月6日 · In this study, spherical imine-linked covalent organic frameworks (COFs) were fabricated from 2,5-dimethoxybenzene-1,4-dialdehyde (DMTP) and 1,3,5-tris (4-aminophenyl) benzene (TAPB) and named as TAPB-DMTP-COFs. The resulting powders were coated onto bare glass bars via physical-adhesion to obtain TAPB-DMTP-COFs coated stir bars.

2015年9月21日 · An o-dichlorobenzene (o-DCB)/n-BuOH (0.5/0.5 ml) mixture of 1,3,5-tri-(4-aminophenyl)benzene (TAPB) (0.080 mmol, 28.1 mg) and DMTA (0.120 mmol, 23.3 mg) in the presence of an acetic-acid catalyst...

2022年3月16日 · Despite numerous studies in the 2D COF field since 2005 10, all the reported 2D COF structures have been characterized through refining powder X-ray diffraction (PXRD) patterns assisted with...

2023年12月19日 · For proof-of-concept applications, we utilized TFB-TAPB COF powder as a fixed adsorption bed to remove trace amounts of OFX from wastewater (Figure 4g). An efficient setup involved packing a plastic column with 180 mg of TFB-TAPB COF powder and passing a 10 ppm of OFX aqueous solution through the column at a constant flow rate of 0.17 mL min ...

2024年12月22日 · tapb-dmpda 的电子衍射和 x 射线散射表征 受到 HRTEM 观察结果的启发，作者通过选区电子衍射 (SAED) 、小角 X 射线散射 (SAXS) 和三维电子衍射（3DED）对 TAPB-DMPDA 的结构进行了仔细研究（图2）。

2025年3月7日 · We further characterized the CS-UCNPs, TAPB-TPA COF, and UCNP-COF particles using X-ray diffraction (XRD) measurements (Figure S5, Supporting Information). The presence of SiO 2 shells in the CS-UCNPs was confirmed by the broad SiO 2 diffraction signal ≈20°. Additionally, distinct diffraction peaks of the CS-UCNPs were observed only in the ...

机理研究表明，tapb-dmtp-cof壳给出的多层柱状通道可以有效地促进tbhq分子向活性co 3+的扩散网站。 在最佳条件下，电流响应表现出两个线性动态范围，即0.05-1.0和1.0-400μmolL -1，检测极限低至0.02μmolL -1（S / N = 3）。
