This study is focused on applying fundamental principles to design and develop materials that can successfully capture and destroy gaseous pollutants from various industrial sources. The use of novel materials that can reduce pollutants in a single integrated unit has the potential to reduce the energy consumption compared to current processes. Results of this study will guide the design and manufacture of high-performance materials for use in industrial pollution control processes that convert toxic compounds to benign products while meeting the environmental standards.This experimental and modeling effort will be focused on both material and process design and development. Specifically, the PIs will synthesize hierarchical mixed-metal oxides (MMOs), deposited with mono and bimetallic nanoparticles (noble and transition metals), using atomic layer deposition (ALD) techniques. The ALD-designed hybrid adsorbent-catalyst materials with hierarchical pore structure are used in the removal of aromatic hydrocarbons, such as benzene, toluene, and xylene, known as BTX compounds, from air in a TSA system. Such hybrid materials will act as a selective mass sink for the adsorbate to create favorable concentration profiles for the oxidation reaction, which will in turn provide heat to regenerate the hybrid materials during the desorption step, thus effectively conserving energy through efficient heat integration. The PIs will also address the design, configuration, process modeling and optimization of the TSA process to improve capture-oxidation efficiency and enable significant reductions in the abatement cost through synergistically exploiting the inherent advantages of each technology. The educational and outreach plan will serve as a platform for graduate, undergraduate and high school students, especially from underrepresented groups, to develop interest in cutting-edge scientific research. The PIs will develop an integrated education and outreach program to incorporate research outcomes into existing coursework and provide research experiences to high school students from Missouri through the Summer Research Academy program.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该研究的重点是应用基本原理设计和开发能够成功捕获和破坏各种工业来源的气态污染物的材料。 与目前的工艺相比，使用可以在单个集成单元中减少污染物的新型材料有可能降低能耗。 这项研究的结果将指导设计和制造高性能材料，用于工业污染控制过程，将有毒化合物转化为良性产品，同时符合环境标准。这项实验和建模工作将集中在材料和工艺设计和开发。具体而言，PI将合成分层混合金属氧化物（MMO），使用原子层沉积（ALD）技术沉积单和双纳米颗粒（贵金属和过渡金属）。ALD设计的具有分级孔结构的混合吸附剂-催化剂材料用于在TSA系统中从空气中去除芳烃，例如苯、甲苯和二甲苯，称为BTX化合物。这样的杂化材料将充当吸附物的选择性质量阱，以产生用于氧化反应的有利浓度分布，这又将在解吸步骤期间提供热以再生杂化材料，从而通过有效的热整合有效地节省能量。PI还将解决TSA工艺的设计、配置、工艺建模和优化问题，以提高捕获氧化效率，并通过协同利用每种技术的固有优势来显著降低减排成本。教育和外联计划将为研究生、本科生和高中生，特别是代表性不足群体的学生提供一个平台，培养他们对尖端科学研究的兴趣。PI将开发一个综合教育和推广计划，将研究成果纳入现有的课程，并通过夏季研究学院计划为来自密苏里州的高中生提供研究经验。该奖项反映了NSF的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。
