Surface Chemical Synthesis of Catalytic Structures

西北大学的Peter Stair教授在化学系化学催化（CAT）项目的支持下，利用低温原子层沉积（ALD）技术研究与合成催化结构相关的表面化学。本研究的具体目标是：(1)利用低温原子层沉积（ALD）技术制备具有可控结构的非均相催化剂；(2)利用一套表面分析工具表征ald生长材料的表面化学性质；(3)研究与能量和环境相关的简单分子的催化化学转化，并将催化性能与ald合成的催化剂的结构和组成联系起来。该项目将提供基本键激活反应的基本信息，以及这些纳米级催化系统在原子水平上催化活性位点的性质。它还将使人们更好地了解与能源和化学工业有关的实用催化剂的结构和活性。参与该项目的学生将接受表面科学和催化方面的高技术培训。通过与阿贡国家实验室的科学家们的交流，他们也将在多相催化方面获得更广阔的视野。

Professor Peter Stair of Northwestern is supported by the Chemical Catalysis (CAT) program in the Division of Chemistry to investigate the surface chemistry associated with the synthesis of catalytic structures using low-temperature atomic layer deposition (ALD) techniques. The specific aims of the proposed research are: (1) to prepare heterogeneous catalysts with controlled structures of materials deposited on flat substrates using low-temperature atomic layer deposition (ALD) techniques; (2) to characterize the surface chemistry of the ALD-grown materials using a suite of surface analysis tools; and (3) to study the catalytic chemical transformations of simple molecules relevant to energy and the environment and correlate the catalytic performance with the structure and composition of the ALD-synthesized catalysts.The project will provide fundamental information on elementary bond activation reactions and on the nature of the catalytically active sites of these nanoscale catalytic systems at the atomic level. It will also lead to a better understanding of the structure and activity of practical catalysts of relevance to energy and the chemical industry. The students involved in the project will be provided with highly technical training in surface science and catalysis. They will also gain a broader perspective on heterogeneous catalysis as a result of interactions with scientists at Argonne National Laboratory.
