Abstract

This work involved introducing defect states into the electronic structure of g-C₃N₄ by Fe doping to create a piezoelectric effect in addition to its photocatalytic properties, thereby increasing the transfer of photoinduced charge carriers and achieving an effective piezophoto-catalytic degradation toward MB dye. Noticeably, Fe-doped g-C₃N₄ (FeCN) catalyst (with 5 % doping) possesses great piezophoto-catalytic degradation performance, decomposing 97.7 % of MB in 60 min. ^•O₂⁻ and ^•OH radicals were the key reactive components as stated by the trapping experiments. Moreover, a degradation efficiency of 92.5 % was still achieved after the fifth round, representing a good durability of assembled FeCN piezophotocatalyst has been ensured.

fe掺杂g-C3N4作为降解有机染料的稳压光催化剂体系的组装

这项工作涉及通过Fe掺杂在g-C3N4的电子结构中引入缺陷态，在其光催化性能之外产生压电效应，从而增加光诱导载流子的转移，并实现对MB染料的有效压电催化降解。值得注意的是，掺铁5%的g-C3N4 （FeCN）催化剂具有良好的压电催化降解性能，在60 min内分解了97.7%的MB。捕获实验表明，•O2−和•OH自由基是关键的活性成分。并且，在第5轮之后，降解效率仍然达到92.5%，说明组装的FeCN压电催化剂具有良好的耐久性。

期刊介绍： The Journal of Molecular Structure is dedicated to the publication of full-length articles and review papers, providing important new structural information on all types of chemical species including: • Stable and unstable molecules in all types of environments (vapour, molecular beam, liquid, solution, liquid crystal, solid state, matrix-isolated, surface-absorbed etc.) • Chemical intermediates • Molecules in excited states • Biological molecules • Polymers. The methods used may include any combination of spectroscopic and non-spectroscopic techniques, for example: • Infrared spectroscopy (mid, far, near) • Raman spectroscopy and non-linear Raman methods (CARS, etc.) • Electronic absorption spectroscopy • Optical rotatory dispersion and circular dichroism • Fluorescence and phosphorescence techniques • Electron spectroscopies (PES, XPS), EXAFS, etc. • Microwave spectroscopy • Electron diffraction • NMR and ESR spectroscopies • Mössbauer spectroscopy • X-ray crystallography • Charge Density Analyses • Computational Studies (supplementing experimental methods) We encourage publications combining theoretical and experimental approaches. The structural insights gained by the studies should be correlated with the properties, activity and/ or reactivity of the molecule under investigation and the relevance of this molecule and its implications should be discussed.
