项目摘要

This award supports cooperative research on ammonia synthesis catalysts to be conducted by Dr. Michel Boudart of Stanford University and Prof. Daniel Loffler of the University of Mar del Plata, Argentina. Ammonia is synthesized on reduced-iron catalysts. Even a small improvement in the process would have considerable economic impact as the need for nitrogen fertilizers grows with the need to feed a growing world population. In this work, commercial catalysts will be characterized using an array of modern techniques including Auger and Mossbauer spectroscopies, and electron microscopy. X-ray absorption (XAS) will be used to study the structure of the catalysts in situ while the reaction is taking place. A better understanding of the catalyst will help the formulation of better catalysts. The ex-situ (Auger, SEM and Mossbauer) characterization will take place in Argentina and the XAS work will be done at Stanford. In this way the facilities of each laboratory will complement those of the other. Both of the researchers have had extensive research experience in catalysis: Dr. Boudart particularly in ammonia synthesis and XAS techniques and Prof. Loffler in the other techniques and in ammonia synthesis, as well. Therefore, they will benefit from each other's expertise and from the shared laboratory capabilities.

该奖项支持氨的合作研究由Michel博士进行的合成催化剂斯坦福大学的布达特和丹尼尔教授阿根廷马德普拉塔大学的Loffler说。氨是在还原铁催化剂上合成的。即使是在这个过程中的一个小改进，相当大的经济影响，因为需要氮肥料随着需要的增长而增长，世界人口。在这项工作中，商业催化剂将使用一系列现代包括俄歇和穆斯堡尔谱光谱学和电子显微镜。 x射线吸收（XAS）将用于研究结构在反应进行的同时，地方更好地了解催化剂将有助于配制更好的催化剂。非原位（俄歇、扫描电镜和穆斯堡尔）将在阿根廷进行表征， XAS的工作将在斯坦福大学完成。以这种方式每个实验室的设施将补充另一两位研究人员都进行了广泛的催化研究经验：Boudart博士特别是在氨合成和XAS技术中和教授Loffler在其他技术和氨合成也是。因此，他们将从彼此的专业知识和共享实验室能力。
