nanoporous crystal12CaO·7 Al_2 O_3（C12A7） is able to discharge generate strong and high purity oxygen anions （O^-） beam under reduced pressure。O^-的各种应用，如VOCs气体分解、氮氧化物、硫氧化物去除、类固醇在大气压力下被操作。However，O^-离子或相关物种的发射在大气压力下没有被评估。在本研究中，我们发现了C12 A7薄膜涂层上的负离子物种发射的特征，在大气压力下由四角杆质量光谱仪检测。负离子物种已被确认，即使在大气压力下也会被激活。它支持检测到的负离子簇，如O^-（H_2O）_n、O_2^-（H_2O）_n和CO_4^-（H_2O）_n，是由从加热器中产生的负离子的反应产生的。O^-应用也是在本研究中开发的。可通过C12 A7删除气体相应用、PFCs、VOCs、氮氧化物和硫氧化物化学品。O^-从C12 A7中产生，被加速了这些香料的氧化，反应温度被降低。液体相位反应的应用也是被证明的。O^- water （OW） was prepared by bubbling of O^-/argon flux into deionized water。OW可能不活跃的E。大肠杆菌，在开发对食物、水或热敏感材料的微生物分解方法中可能很有用。

The nanoporous crystal 12CaO・7Al_2O_3 (C12A7) is able to discharge generate strong and high purity oxygen anions (O^-) beam under reduced pressure. Various applications of O^-, such as VOCs gas decompositions, NOx, SOx removal, sterilization are operated under atmospheric pressure. However, the emission of O^- ion or related species under atmospheric pressure have not been evaluated. In this study, the characteristics of negative ion species emissions from the C12A7 membrane-coated on the ceramic heater under atmospheric pressure were investigated by quadrupole mass spectrometry. Negative ion species were confirmed to be emitted even under atmospheric pressure. It was supposed that the detected negative ion clusters, such as O^-(H_2O)_n, O_2^-(H_2O)_n, and CO_4^-(H_2O)_n, were generated by the reaction of negative ions emitted from the heater with impurities in He gas.The O^- applications were also developed in this study. For the gas phase applications, PFCs, VOCs, NOx and SOx chemical spices can be removed by C12A7. The O^- generated from C12A7 were accelerated an oxidation of these spices, and the reaction temperature were decreased. Applications of liquid phase reaction were also demonstrated. O^- water (OW) was prepared by bubbling of O^-/argon flux into deionized water. The OW could inactivate E. coli, which may be potentially useful in developing a novel approach for the microbial decontamination of food, water or heat-sensitive material.
