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 stability...

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.

2021年6月1日 · In this work, a core-shell material composed of TAPB-DMTP-COF (TAPB, 1,3,5-tris(4-aminophenyl)benzene; DMTP, 2,5-dimethoxyterephaldehyde) core and conducting polymer shell, TAPB-DMTP-COF@PANI, was synthesized solvothermally using a polymerization method.

2024年4月18日 · XPS was used to investigate the electronic interactions between Fe and Ni ions in COF-Bpy@FeNi. Ni is normally considered to be the primary catalytic site for the OER in FeNi-based bimetallic electrocatalysts, with ferric ions regulating the electronic structure of Ni by changing the Ni 2p binding energy [ 55 , 56 ].

2021年8月20日 · The interaction between amino groups in TiATA core and aldehyde groups in the LZU1 shell was confirmed by X-ray photoelectron spectroscopy (XPS) analysis. The control experiment further proved the critical role of amino functionalities in stabilizing the TiATA@LZU1 core–shell structure.

2023年8月25日 · In this study, we present the design and fabrication of a COFs-aerogel with unique slice-layer structure and its application as a regenerative dSPE adsorbent material for ultra-trace QAs (i.e., norfloxacin (NOR), ofloxacin (OFL), enrofloxacin (ENR), and flumequine (FLU)) emitted from water and food samples.

transform infrared spectra (FTIR), X-ray photoelectron spectroscopy (XPS), transmission electron microscopy (TEM) to verify their structure and morphology. Then we applied TAPB-DMTP-COF@PANI as an electrochemical amplifier for the determination of drug molecule.

x射线光电子能谱（xps）： 1) CoTPP-DMTP-COF的XPS谱图显示在398.9 eV和398.3 eV处有峰，分别对应于吡咯N−Co和亚胺N=C。 2) DABCO®CoTPP-DMTP-COF的XPS谱图显示在398.1 eV、398.6 eV和400.6 eV处有峰，分别对应于亚胺N=C、吡咯N−Co和轴向DABCO N−Co。

In this research work, new composite materials based on magnesium phosphate cement (MPC) were developed to evaluate the retention of fluorine from wastewater. This material was prepared with dead...

As depicted in Fig. 5b, the I 3d XPS spectra of I 2 @MC-DMTP-TPB COF exhibited I 3d 3/2 binding energies at 632.3 and 630.3 eV, as well as I 3d 5/2 signals at 620.8 and 618.8 eV, corresponding...
