Abstract

Herein, Fe₃Ce₂/NaY catalysts for catalyzing the oxidative degradation of quinoline by ozonation were prepared by the impregnation method and characterized by X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), transmission electron microscopy (TEM) and energy dispersive spectroscopy (EDS). The Fe₃Ce₂/NaY had high activity for catalyzing ozone oxidation, the quinoline removal efficiency reached 99.14 % in 10 min for the 90 mg/L quinoline solution. Meanwhile, the catalyst had good reusability and the COD removal performance was almost unchanged during four cycles of reaction. In the catalytic ozone oxidation system, the reaction kinetics of quinoline degradation were consistent with a pseudo-first-order reaction. Surface hydroxyl groups facilitated the adsorption and decomposition of O₃, thus promoting the generation of reactive oxygen species (ROS) and improving the quinoline mineralization efficiency, which played an important role in the catalytic process. The degradation intermediates were also investigated using liquid chromatography-mass spectrometry (LC-MS) and ion chromatography.

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.
