Adsorption Studies on Carbon Nanotubes Using NMR Spectroscopy

化学部的先进材料计划和EPSCoR办公室的激发竞争性研究的实验计划将这一奖项授予新墨西哥州采矿与技术研究所。获得该奖项后，Tanja Pietrass教授将利用原位固态核磁共振波谱研究碳纳米管对氢、氧、一氧化二氮和氨的吸附，充分利用偶极和四极耦合研究、化学位移和驰豫时间测量。气体动力学将利用二维交换光谱在不同温度和气体密度条件下进行探索。这些研究结果将有助于了解不同气体在碳纳米管上的存储容量、电子结构和结合动力学。新墨西哥矿业与技术学院有一个庞大的少数族裔学生群体，主要是西班牙裔和美洲原住民，这一奖项将有助于他们的研究、培训和教育。碳纳米管对不同气体的吸收动力学将使用固体核磁共振波谱进行研究，充分利用偶极和四极耦合研究、化学位移和驰豫时间测量。这些研究将为碳纳米管的存储容量、电子结构和结合动力学提供基础信息。这项研究的结果可以在气体存储方面找到应用，例如用于燃料电池、气体分离和气体传感器材料的氢气。此外，该研究计划将为材料和表面化学方面的本科生和研究生提供多学科的教育和培训机会，新墨西哥州采矿与技术学院的大量代表不足的少数族裔将从这些研究活动中受益。

The Advanced Materials Program in the Division of Chemistry and the Experimental Program to Stimulate Competitive Research in the Office of EPSCoR make this award to New Mexico Institute of Mining and Technology. With the award, Professor Tanja Pietrass will study the adsorption of hydrogen, oxygen, nitrous oxide and ammonia by carbon nanotubes using in situ solid-state NMR spectroscopy, exploiting the full complement of dipolar and quadrupolar coupling studies, chemical shifts and relaxation time measurements. Gas dynamics will be probed using two-dimensional exchange spectroscopy under variable temperature and gas density conditions. Results from these studies will be beneficial to understand the storage capacity, electronic structure and binding kinetics of different gases by carbon nanotubes. New Mexico Institute of Mining and Technology has a large underrepresented minority student body, mainly Hispanics and Native Americans, and this award will help in their research training and education. Absorption kinetics of different gases by carbon nanotubes will be studied using solid-state NMR spectroscopy, exploiting the full complement of dipolar and quadrupolar coupling studies, chemical shifts and relaxation time measurements. These studies will provide fundamental information about storage capacity, electronic structure and binding kinetics of carbon nanotubes. Results from this research could find applications in gas storage, e.g. hydrogen gas for fuel cells, gas separations, and as gas sensor materials. In addition, the research program will provide multidisciplinary education and training opportunities to undergraduate and graduate students in material and surface chemistries, and large number of under represented minorities attending the New Mexico Institute of Mining and Technology will benefit from these research activities.
