研究目的
To investigate the role of ferrocene linkage in facilitating charge separation and enhancing photocatalytic degradation of pollutants in conjugated microporous polymers.
研究成果
Fc-based CMPs with integrated ferrocene linkages suppress electron-hole recombination, facilitate ROS generation, and exhibit superior photocatalytic degradation of pollutants like methylene blue and CEES compared to controls and commercial TiO2, offering a potential platform for sustainable photocatalyst design.
研究不足
The study notes that further optimization is needed to improve photocatalytic activities towards CEES and other warfare agents. Trace Pd and Cu residues from catalysis were present, and molar ratios were estimated due to insolubility, potentially affecting accuracy.
1：Experimental Design and Method Selection:
The study involved synthesizing Fc-based CMPs via palladium-catalyzed Sonogashira-Hagihara cross-coupling copolymerization to incorporate ferrocene into polymer backbones, with systematic engineering of optical energy gaps.
2：Sample Selection and Data Sources:
Samples included Fc-TEB-CMP, Fc-TPE-CMP, Fc-Py-CMP, Fc-CBZ-CMP, and controlled polymers (DBB-TEB-CMP, DBB-TPE-CMP, P(Fc-DEB)), using building blocks like 1,3,5-triethynylbenzene, tetrakis(4-ethynylphenyl)ethene, etc.
3：List of Experimental Equipment and Materials:
Equipment included Fourier transform infrared attenuated total reflection spectrometer, solid-state 13C cross-polarization magic angle spinning NMR, N2 sorption isotherm measurements at 77 K, UV-vis diffuse reflectance spectroscopy, valence band X-ray photoelectron spectroscopy, photoluminescence detection, electron spin resonance spin trapping methods, and fluorescent probes (coumarin, p-hydroxyphenylacetic acid, singlet oxygen sensor green). Materials included palladium and copper catalysts, organic solvents, and pollutants (methylene blue, 2-chloroethyl ethyl sulfide).
4：Experimental Procedures and Operational Workflow:
Synthesis of polymers, characterization (FTIR, NMR, BET surface area, pore size distribution), evaluation of molecular orbitals, adsorption and photocatalytic degradation tests under visible and simulated solar light, scavenger experiments to identify reactive species, and recycling tests.
5：Data Analysis Methods:
Data analyzed using pseudo-second-order model for adsorption kinetics, QSDFT for pore size distribution, and statistical methods for photocatalytic efficiency comparisons.
