The Chemical Catalysis Program supports Professor Robert J. Madix at Harvard University for a research project that will develop the fundamental basis for simple, novel heterogeneously catalyzed reactions for the transformation of amides, imines, nitriles and aziridines over copper, silver and gold surfaces through understanding of the kinetics and mechanism of the surface reactions of nitrogen-containing molecules. The proposed studies are based on fundamental principles of surface reactivity discovered and developed in previous NSF-supported work. Amidization, iminization, nitrilation and aziridination reactions facilitated by these group IB metals will be studied utilizing well defined single crystal surfaces. This research will provide a molecularly based understanding of the elementary reaction steps of these complex synthesis reactions. They have the potential for transforming existing technologies into more energy efficient and environmentally benign processes.With the support of the Chemical Catalysis Program in the Chemistry Division at the National Science Foundation, Dr. Madix will perform research that will have a significant impact on important chemical transformations for the industrial sector with significant outcomes of improved catalyst selectivity, reduced waste, and potentially lower energy consumption. The proposed research is important to the development of processes critical to maintaining leadership in the multibillion dollar chemical industry in the United States and to the reduction in energy use. Broader impacts of the research has as an outcome the training and professional development of postdoctoral students and the training of both women and minority students. Professor Madix will include undergraduates in his research through the REU program at Harvard and will conduct coordinated activities with local high schools to stimulate the interest of minority high school students in physical science. Harvard University's existing partnerships with both The Engineering School at the Hyde Park Educational Complex in Boston and the Cambridge Rindge and Latin School will be utilized.

化学催化项目支持哈佛大学Robert J. Madix教授的一项研究项目，该项目将通过对含氮分子表面反应的动力学和机制的理解，为在铜、银和金表面上转化酰胺、亚胺、腈和氮嘧啶的简单、新颖的非均相催化反应发展基础。拟议的研究是基于在以前nsf支持的工作中发现和发展的表面反应性的基本原理。这些IB族金属促进的酰胺化、最小化、硝化和叠氮化反应将利用明确的单晶表面进行研究。这项研究将为这些复杂合成反应的基本反应步骤提供基于分子的理解。它们有可能将现有技术转变为更节能和无害环境的工艺。在美国国家科学基金会化学部化学催化项目的支持下，Madix博士将进行的研究将对工业部门的重要化学转化产生重大影响，并在提高催化剂选择性、减少浪费和潜在降低能耗方面取得重大成果。拟议的研究对于发展对保持美国数十亿美元化学工业的领导地位和减少能源使用至关重要的过程非常重要。这项研究对博士后的培养和专业发展，以及对女性和少数民族学生的培养产生了更广泛的影响。Madix教授将通过哈佛大学REU项目让本科生参与他的研究，并将与当地高中开展协调活动，以激发少数民族高中生对物理科学的兴趣。哈佛大学与波士顿海德公园教育综合体工程学院和剑桥林奇拉丁学院的现有合作伙伴关系将得到利用。
