Preparation and Characterization of Storage and Emission Functional Material of Chlorine Anion: [Ca24Al28O64]4+ (Cl)3.80(O2)0.10

Abstract

A storage and emission functional material of [Ca24Al28O64]4+(Cl)3.80(O2)0.10 (C12A7-Cl), was prepared by the solid-state reactions of CaCO3, -Al2O3, and CaCl2 in Cl2/Ar mixture atmosphere. The anionic species stored in the C12A7-Cl material were dominated by Cl, about (2.210.24) 1021 cm3, accompanied by a small amount of O2, O, and O2, measured via ion chromatography, electron paramagnetic resonance, and raman spectra measurements. These results also corroborate identification of time-of-flight mass spectroscopythe anionic species emitted from the C12A7-Cl surface were dominated by the Cl (about 90%) together with a small amount of O and electrons. The structure and morphological alterations of the material were investigated via X-ray diffraction and field emission scanning electron microscope, respectively.
