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, γ-Al2O3, and CaCl2 in Cl2/Ar mixture atmosphere. The anionic species stored in the C12A7-Cl- material were dominated by Cl-, about (2.21±0.24)×1021 cm-3, 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 spectroscopy—the 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.

摘要:
通过碳酸钙、γ-三氧化二铝、氯化钙在氯气/氩气混合气气氛下的固态反应制备了一种氯负离子存储-发射功能材料[Ca24Al28O64]4+·(Cl-)3.80(O2-)0.10(C12A7-Cl-).通过离子色谱、电子顺磁共振、拉曼光谱验证,C12A7-Cl-材料中存储的负离子主要是氯负离子,浓度为(2.21±0.24)×1021 cm-3,此外还有小部分的氧二价负离子、氧负离子、氧分子负离子.这与通过飞行时间质谱得到的结果一致:从C12A7-Cl-材料表面发射出的负离子主要是氯负离子(大约90%),还有小部分的氧负离子和电子.材料结构和表观变化分别由X射线衍射和场发射扫描电子显微镜表征
