9724169 Campbell This U.S.-Brazil award will support a research collaboration between Dr Charles T. Campbell and Dr. David G. Castner of the University of Washington to work with Professor Martin Schmal at the Federal University in Rio de Janeiro, Brazil on the influence of support and additives on Pd-based catalysts for emission control. The goal of this project is to clarify catalytic processes which are relevant to environmental protection. They will investigate the relationships between the activity of a series of palladium-based catalysts and their surface structure. They will prepare catalysts and test them with classic techniques, such as activity measurements, surface areas, temperature programmed reduction, and porosity. Their surface structure and composition will be characterized using facilities at the University of Washington, which are not available in Brazil. Schmal's group has extensive experience in the characterization of supported catalysts with reactor studies, selective chemisorption, temperature programmed reduction and temperature programmed oxidation and adsorbate structure. The U.S. group brings expertise in the area of surface analysis and the surface science of catalysis. Findings from this research will be useful in developing commercial supported catalysts with optimum structures and maximum emission control activity. The full kinetic and mechanistic information will identify critical barriers and operating conditions that limit emission control activity, and possibly provide a basis for developing strategies to overcome barriers and limitations. The results will also provide information about properties that would be desirable to have for a promotion of emission control catalysts. * * *

9724169坎贝尔美国-巴西奖将支持查尔斯·T.坎贝尔和大卫G.华盛顿大学的Castner与巴西里约热内卢联邦大学的Martin Schmal教授合作，研究载体和添加剂对用于排放控制的Pd基催化剂的影响。 该项目的目标是澄清与环境保护有关的催化过程。 他们将研究一系列钯基催化剂的活性与其表面结构之间的关系。 他们将制备催化剂，并使用经典技术对其进行测试，如活性测量，表面积，程序升温还原和孔隙率。 将利用华盛顿大学的设施来确定其表面结构和成分的特征，巴西没有这些设施。 Schmal的研究小组在负载型催化剂的表征、反应器研究、选择性化学吸附、程序升温还原和程序升温氧化以及吸附质结构方面拥有丰富的经验。 该美国集团带来了表面分析和催化表面科学领域的专业知识。 本研究的结果将有助于开发具有最佳结构和最大排放控制活性的商业负载催化剂。 完整的动力学和机理信息将确定限制排放控制活动的关键障碍和操作条件，并可能为制定克服障碍和限制的战略提供基础。 该结果还将提供关于对于促进排放控制催化剂将期望具有的性质的信息。 * * *
