项目摘要
CBET-0754979GubbinsThis NSF award by the Chemical and Biological Separations program supports work by Professors Teresa J. Bandosz and Keith E. Gubbins at CUNY City College and North Carolina State University, respectively, to investigate and design novel reactive adsorbents for the removal of toxic gases. Growing concerns about the environment and terrorist attacks prompt a search for effective adsorbents for removal of small molecule toxic gases, such as ammonia, hydrogen sulfide, sulfur dioxide, and carbon monoxide. These are usually to be removed under ambient conditions in the presence of moisture, conditions where physical adsorption forces are weak. In the research program proposed here we will use a combined experimental and theoretical approach to explore toxic gas removal using reactive adsorption, by designing graphite oxide materials with functional surface groups that are optimal for removal of these gases. The experimental work will be carried out at CUNY City College, and the theoretical program at North Carolina State University. We seek to determine the fundamental mechanism, at the atomic and electronic levels, of reactive adsorption/intercalation of small molecule toxic gases on these materials. The graphite oxides will be synthesized and modified to achieve suitable microporosity and reactive/catalytic surface properties. The fundamental theoretical studies will guide the synthesis of materials with appropriate pore structures and surface functionalilties. In return, the experimental findings will suggest new directions of enquiry for the theoretical studies. Studies will be made both in the absence and presence of water, thus mimicking practical conditions in industry.This will be the first concerted combined experimental and theoretical investigation of these systems. The research is expected to lead to improved functionalized adsorbents, which may find application in other scientific challenges where the separation of reactive molecules is involved. In addition to developing experimental and theoretical algorithms to design effective adsorbents, the results may find wide applications in air cleaning, energy storage, and fuel cell technology. The materials developed may also find application as gas sensors. Changes in electrical conductivity due to the presence of such small molecules intercalated within the graphite interlayer space can be used to detect toxic gases at low concentrations.Two graduate students (one at CCNY and one at NCSU) and one undergraduate student (CCNY) will work on the project. Since CCNY is a minority serving institution there is a high probability that students from underrepresented groups will be involved in the research, which will have a positive effect on development of environmental awareness in the minority group. Other important educational aspects are the development of new environmental chemistry experiments by the undergraduate student involved in the research (independent research undergraduate project), and the development of new theoretical methods for the surface characterization of functionalized materials and for reaction with diffusion in nano-structured materials.
CBET-0754979 Gubbins化学和生物分离项目的NSF奖项支持Teresa J. Bandosz和基思E. Gubbins分别在纽约市立大学和北卡罗来纳州州立大学,研究和设计新型反应吸附剂去除有毒气体。 对环境和恐怖袭击的日益关注促使人们寻找有效的吸附剂来去除小分子有毒气体,如氨、硫化氢、二氧化硫和一氧化碳。这些通常在有水分存在的环境条件下除去,在这种条件下物理吸附力很弱。在这里提出的研究计划中,我们将使用实验和理论相结合的方法来探索使用反应吸附去除有毒气体,通过设计具有最适合去除这些气体的功能表面基团的氧化石墨材料。 实验工作将在纽约市立大学进行,理论项目将在北卡罗来纳州州立大学进行。 我们试图确定的基本机制,在原子和电子水平上,这些材料上的小分子有毒气体的反应吸附/嵌入。氧化石墨将被合成和改性,以实现合适的微孔性和反应/催化表面性能。基础理论研究将指导具有适当孔结构和表面功能的材料的合成。 反过来,实验结果也为理论研究提供了新的探索方向。 研究将在无水和有水的情况下进行,从而模拟工业中的实际条件。这将是这些系统的首次协调的实验和理论研究。 该研究有望改进功能化吸附剂,这可能会在涉及反应分子分离的其他科学挑战中找到应用。除了开发实验和理论算法来设计有效的吸附剂外,研究结果还可能在空气清洁,能量储存和燃料电池技术中得到广泛应用。所开发的材料也可以用作气体传感器。由于这种小分子插入石墨层间空间而导致的电导率变化可用于检测低浓度的有毒气体。两名研究生(一名来自CCNY,一名来自NCSU)和一名本科生(CCNY)将参与该项目。由于CCNY是一个少数民族服务机构,来自代表性不足群体的学生很有可能参与研究,这将对少数民族环境意识的发展产生积极影响。其他重要的教育方面是参与研究的本科生开发新的环境化学实验(独立研究本科生项目),以及开发功能化材料表面表征和纳米结构材料中扩散反应的新理论方法。
