Abstract

We report an investigation of the synthesis of a cobalt aluminate spinel composite from the heat-induced collapse of cobalt ion-exchanged sodium zeolite X. The work presented here adds to earlier studies by illustrating that by careful control of synthesis and reaction conditions, both the phase composition and crystallite size of the spinel can be controlled. The spinel crystallites grow within siliceous materials formed by the collapse of the zeolite framework, with the crystalline particles being completly shrouded by the siliceous matrix.

Graphical abstractWe report the synthesis and characterisation of cobalt aluminate spinel micro-crystals, formed by the heat-induced collapse of cobalt ion-exchanged zeolite X precursors; the resulting transparent blue micro-crystals are covered in a siliceous coating which may reduce the potential environmental impact of the included cobalt compounds.Figure optionsDownload full-size imageDownload as PowerPoint slide
