Abstract

A simple method for the preparation of a foam glass/CoFe₂O₄ composite material has been proposed for the first time. We have demonstrated the conceptual feasibility of utilizing glass scrap and plant ash and slag for the preparation of cellular glassy materials suitable for use as supports of catalytically active substances. The synthesized composite materials have been characterized by X-ray diffraction and electrode microscopy. A possible mechanism of cobalt(II) ferrite structure formation on the surface of foam glass has been discussed. We have studied the photocatalytic properties of the synthesized materials for the oxidative destruction of an organic dye in the presence of hydrogen peroxide. The synthesized support has been shown to be inert in the catalytic process studied. The foam glass/CoFe₂O₄ composite material exhibits high catalytic activity under the conditions studied here: complete removal of the organic dye from a solution takes 210 min after the reaction onset.

基于玻璃屑，植物灰和矿渣的泡沫玻璃在催化活性材料制备中的应用

摘要

一种制备泡沫玻璃/ CoFe ₂ O _4的简单方法复合材料是第一次提出。我们已经证明了利用玻璃屑，植物灰和炉渣制备适于用作催化活性物质载体的多孔玻璃状材料的概念可行性。合成的复合材料已通过X射线衍射和电极显微镜表征。讨论了在泡沫玻璃表面形成钴（II）铁氧体结构的可能机理。我们已经研究了合成材料在过氧化氢存在下对有机染料的氧化破坏的光催化性能。已证明合成的载体在所研究的催化过程中是惰性的。泡沫玻璃/ CoFe ₂ O ₄ 复合材料在此处研究的条件下表现出高催化活性：反应开始后210分钟从溶液中完全去除有机染料。
