摘要

铁基异相催化剂在废水处理的 Fenton 类反应中具有广阔的应用前景，但其可回收性阻碍了其实际应用，而且其高性能的基本起源机制和结构-活性关系仍有待进一步阐明。本文利用 NH4Cl 添加剂制备了一系列含 Fe2(OH)3Cl 的整体石催化剂，当 H2O2 作为氧化剂时，这些催化剂在亚甲基蓝和罗丹明 B 的 Fenton 类降解中的性能明显高于 Fe3O4 催化剂。含 Fe2（OH）3Cl 的整体催化剂可在降解实验中重复使用四次，而其活性不会大幅降低。对催化降解过程中产生的活性自由基进行了研究。

Fe-based monolithic catalysts for Fenton-like degradation of organic dyes: The important role of Fe2(OH)3Cl species

Fe-based heterogeneous catalysts are promising in Fenton-like reactions for wastewater treatment, but their practical application is hindered by their recyclability, and the fundamental mechanisms for origin of the high performance and the structure-activity relationships remain to be elucidated further. In this paper, we prepared a series of Fe₂(OH)₃Cl-containing monolith catalysts by the use of NH₄Cl additives, which gave significantly higher performance than the Fe₃O₄ counterparts in Fenton-like degradation of methylene blue and rhodamine B when H₂O₂ was used as oxidant. The Fe₂(OH)₃Cl-containing monolith catalyst can be reused four cycles in the degradation experiments without big loss in their activity. The active radicals generated during process of the catalytic degradation were studied.

期刊介绍： Vacuum is an international rapid publications journal with a focus on short communication. All papers are peer-reviewed, with the review process for short communication geared towards very fast turnaround times. The journal also published full research papers, thematic issues and selected papers from leading conferences. A report in Vacuum should represent a major advance in an area that involves a controlled environment at pressures of one atmosphere or below. The scope of the journal includes: 1. Vacuum; original developments in vacuum pumping and instrumentation, vacuum measurement, vacuum gas dynamics, gas-surface interactions, surface treatment for UHV applications and low outgassing, vacuum melting, sintering, and vacuum metrology. Technology and solutions for large-scale facilities (e.g., particle accelerators and fusion devices). New instrumentation ( e.g., detectors and electron microscopes). 2. Plasma science; advances in PVD, CVD, plasma-assisted CVD, ion sources, deposition processes and analysis. 3. Surface science; surface engineering, surface chemistry, surface analysis, crystal growth, ion-surface interactions and etching, nanometer-scale processing, surface modification. 4. Materials science; novel functional or structural materials. Metals, ceramics, and polymers. Experiments, simulations, and modelling for understanding structure-property relationships. Thin films and coatings. Nanostructures and ion implantation.
