Abstract

The efficient degradation of emerging pollutants in water, represented by CBZ, is receiving increasing attention from all sectors of society. Although advanced oxidation reactions represented by Fenton reaction can efficiently degrade emerging pollutants, the problem of iron sludge that comes with it is hindering the further promotion of this technology. Herein, UiO-66(Zr)-2OH material was synthesized by hydrothermal method and loaded with Pd0 NPs on the surface of the material by in situ reduction. The MOFs-H2-Accelerated Catalytic Fenton system was constructed by accelerating the regeneration of Fe(II) in the system by activating the [H] produced by H2 introduced into the system at room temperature and pressure. Within 180 min, the removal of the target pollutant CZB could reach more than 99 % under the condition of only 25 µmol of Fe(II) and 25 mmol of H2O2.

期刊介绍: Applied Catalysis A: General publishes original papers on all aspects of catalysis of basic and practical interest to chemical scientists in both industrial and academic fields, with an emphasis onnew understanding of catalysts and catalytic reactions, new catalytic materials, new techniques, and new processes, especially those that have potential practical implications. Papers that report results of a thorough study or optimization of systems or processes that are well understood, widely studied, or minor variations of known ones are discouraged. Authors should include statements in a separate section "Justification for Publication" of how the manuscript fits the scope of the journal in the cover letter to the editors. Submissions without such justification will be rejected without review.
