Abstract

Fenton-like degradation based on iron catalyst have been developed to remove organic pollutants from wastewater. However, iron-based catalysts still face challenges of poor accessibility and stability of active sites. Here, we report a facile and green method for the preparation of Fe_xCu_(1-x)@HZSM-5 catalyst using ethylenediamine as an organic ligand to stabilize metal species via a combination of solid-state grinding and steam-assisted crystallization methods without organic templates. Due to the confinement of zeolite ZSM-5 framework and synergistic effect of Fe and Cu bimetals, the optimized Fe_0.8Cu_0.2@HZSM-5 catalyst exhibits excellent activity and reusability in the Fenton-like degradation of methylene blue at the neutral condition. Our strategy for fabricating bimetal@zeolite can bring about new thoughts for the preparation of iron-based catalyst with high efficiency for Fenton-like degradation.

ZSM-5包封Fe-Cu双金属氧化物对亚甲基蓝的高效非均相fenton降解

基于铁催化剂的类fenton降解技术已被开发用于废水中有机污染物的去除。然而，铁基催化剂仍然面临活性位点可及性和稳定性差的挑战。在这里，我们报告了一种简单而绿色的方法来制备FexCu(1-x)@HZSM-5催化剂，使用乙二胺作为有机配体，通过固体研磨和蒸汽辅助结晶方法的结合来稳定金属物种，而不使用有机模板。由于ZSM-5分子筛骨架的约束和Fe和Cu双金属的协同作用，优化后的Fe0.8Cu0.2@HZSM-5催化剂在中性条件下具有良好的fenton类降解亚甲基蓝的活性和可重复使用性。我们制造bimetal@zeolite的策略可以为制备高效的类芬顿降解铁基催化剂带来新的思路。

期刊介绍： Microporous and Mesoporous Materials covers novel and significant aspects of porous solids classified as either microporous (pore size up to 2 nm) or mesoporous (pore size 2 to 50 nm). The porosity should have a specific impact on the material properties or application. Typical examples are zeolites and zeolite-like materials, pillared materials, clathrasils and clathrates, carbon molecular sieves, ordered mesoporous materials, organic/inorganic porous hybrid materials, or porous metal oxides. Both natural and synthetic porous materials are within the scope of the journal. Topics which are particularly of interest include: All aspects of natural microporous and mesoporous solids The synthesis of crystalline or amorphous porous materials The physico-chemical characterization of microporous and mesoporous solids, especially spectroscopic and microscopic The modification of microporous and mesoporous solids, for example by ion exchange or solid-state reactions All topics related to diffusion of mobile species in the pores of microporous and mesoporous materials Adsorption (and other separation techniques) using microporous or mesoporous adsorbents Catalysis by microporous and mesoporous materials Host/guest interactions Theoretical chemistry and modelling of host/guest interactions All topics related to the application of microporous and mesoporous materials in industrial catalysis, separation technology, environmental protection, electrochemistry, membranes, sensors, optical devices, etc.
