0967434SchneiderSystems where lean combustion processes are carried out in excess air offer significant fuel efficiency benefits that can contribute to reductions of greenhouse gas (GHG) emissions. However, an important byproduct of lean combustion is NOx (x = 1, 2). While cost-effective technologies have been demonstrated for the remediation of NOx produced at stationary sources, solutions for the aftertreatment of NOx produced by mobile sources including diesel powered vehicles remains a major challenge. One of the most significant aspects is that Platinum-containing catalysts are the most effective catalysts for this operation, and the amount of platinum required makes these catalysts prohibitively expensive. In this proposal which calls for collaboration between PIs Thompson from University of Michigan and Schneider from University of Notre Dame, an industrial partner, General Motors, is added to make it a GOALI proposal as well as a Collaborative one. The intent is to resolve why catalytic activity of about the same magnitude as platinum has been observed with a non-precious metal containing perovskite catalyst originally observed by General Motors scientists, and to determine if rugged, inexpensive catalysts can be demonstrated which could in fact replace platinum. This would be a significant change in our understanding of reactions that are catalyzed by platinum, and on a more practical level, would open up the area of diesel-powered vehicles with the improved efficiencies and reduced GHG emissions expected, as less-expensive catalytic after-treatments or mufflers could be available. The program involves the two universities and the industrial partner at many points of contact and in various phases of the work. Students will benefit from the collaboration and from the contact with industry. In addition the PIs will leverage existing education and outreach programs on the campuses to both interest and educate society about the issue and benefits from success in the project.

0967434Schneidersystems在过量空气中进行精益燃烧过程的燃油效率优势可有助于减少温室气体（GHG）排放。但是，瘦燃烧的重要副产品是nox（x = 1，2）。尽管已经证明了对固定来源生产的NOX的补救的成本效益技术，但包括柴油动力汽车在内的移动资源生产的NOX后处理的解决方案仍然是一个重大挑战。最重要的方面之一是，含铂的催化剂是该操作的最有效的催化剂，所需的铂量使这些催化剂非常昂贵。在这项提案中，呼吁密歇根大学的PIS Thompson与Notre University Dame的Schneider之间的合作，工业合作伙伴，通用汽车，以使其成为目标和协作。目的是解决为什么观察到与铂金大约相同大小的催化活性，其中含有含有钙钛矿的非私致金属最初是由通用电动机科学家观察到的，并且可以确定是否可以证明，是否可以替换耐加强的催化剂铂。这将是我们对铂催化的反应的理解的重大变化，并且在更实际的水平上，将开放柴油动力汽车的区域，其效率提高并减少了GHG排放，因为此后预期的温室气体排放量降低，因为此后且较低的催化性催化剂在 - 可以提供处理或消声器。该计划涉及两所大学和工业合作伙伴在许多接触点和工作的各个阶段。学生将从合作和与行业的接触中受益。此外，PI将利用校园的现有教育和外展计划，以使社会有关该项目的问题以及受益。
