ABSTRACT CTS-9624433 The objective of this research is the design of novel heterogeneous catalysts for emission control applications. In particular, the research focuses on two applications: the removal of NOx via its selective catalytic reduction with hydrocarbons (hydrocarbon-SCR) under excess oxygen ("lean") conditions; and the simultaneous removal of nitrogen oxides (NOx) and chlorinated volatile organic compounds (VOCs). The proposed research uses kinetic and in-situ spectroscopic characterization techniques. The different reaction pathways involved in the overall reaction networks, the reactive intermediates, and the active surface sites are identified. These findings are correlated with the structural properties of existing catalysts and used to provide important leads for the design and synthesis of the next generation of catalytic systems. This research could lead to a novel, hydrothermally stable hydrocarbon-SCR catalyst that would find commercial use in both mobile and stationary emission control applications, while a new bifunctional catalyst for the simultaneous removal of NOx and clilorinated VOCs would find an immediate use in controlling emissions from municipal and medical waste-incineration units and a long-term use in controlling emissions from the chlorochemical and the coating industries. The proposed educational plan includes the development of new courses at both the undergraduate and graduate levels and the continuous involvement of undergraduate and graduate students in research. The new courses include a freshman-level course in chemical manufacturing, a senior-level elective course in environmental engineering, and a graduate-level course in heterogeneous catalysis.

摘要CTS-9624433本研究的目标是设计用于排放控制的新型多相催化剂。特别是，这项研究侧重于两个应用：在富氧条件下通过烃类选择性催化还原(烃-SCR)脱除NOx；同时脱除氮氧化物(NOx)和氯化挥发性有机化合物(VOCs)。拟议的研究使用了动力学和原位光谱表征技术。确定了整个反应网络中涉及的不同反应路径、反应中间体和活性表面位置。这些发现与现有催化剂的结构性质相关联，并用于为下一代催化系统的设计和合成提供重要线索。这项研究可能导致一种新型的水热稳定的碳氢化合物-SCR催化剂，该催化剂将在移动和固定排放控制应用中找到商业用途，而同时去除NOx和氯化VOCs的新的双功能催化剂将立即用于控制城市和医疗废物焚烧单位的排放，并长期用于控制氯化和涂料行业的排放。拟议的教育计划包括在本科生和研究生一级开发新课程，并让本科生和研究生继续参与研究。新课程包括化学制造的大一课程、环境工程的高级选修课程和多相催化的研究生课程。
