The broader impact/commercial potential of this PFI project is the development of a sustainable, environmentally-friendly material for reducing pollution from automobiles. The existing technology used to reduce pollution, a catalytic converter, contains expensive, rare metals and does not perform well when an engine starts. An aerogel is a special lightweight material with many features that make it an attractive addition to a catalytic converter. Aerogel-based catalytic converters would provide an economically attractive and sustainable approach to reducing automotive pollution, and thereby have a significant positive economic and environmental impact on the nation. This project will develop new aerogels to achieve these goals. In addition, the project will develop a research/entrepreneurship practicum to engage students (including those from traditionally underrepresented groups) in developing entrepreneurial ideas and learning about bringing technology developed through fundamental research to the marketplace. This new model for the undergraduate curriculum will provide students with substantial entrepreneurial experience at precisely the point at which such training could have maximal impact: prior to entering graduate school or the STEM workforce.The proposed project will develop and test new aerogel catalysts to be used in the development of a superior technology for reducing automotive pollution. One of the primary technical challenges of the current technology, the catalytic converter, is its inability to minimize or eliminate emissions under cold-start conditions. Aerogels offer many features (high temperature stability, large surface area, low mass and tunable chemistry) that make them viable candidates for an alternative technology and they have been shown to be active in reducing exhaust pollution. By tuning their chemistry, aerogels can be made catalytically active and are effective at promoting conversion of exhaust gas pollutants. The proposed project will address several technical challenges associated with developing this potentially transformative alternative technology to reduce cold-start emissions by: (1) developing catalytically active aerogels with alternate chemistries to improve activation characteristics; (2) demonstrating the high-temperature survivability of these materials (3) investigating the potential of the catalytically active aerogels for lowering thermal inertia; (4) incorporating aerogels into conventional washcoating methods; (5) integrating aerogels into a prototype catalytic converter; and (6) developing transferable models of broad-based training and leadership development in innovation and entrepreneurship for undergraduate STEM students.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

这个PFI项目的更广泛的影响/商业潜力是开发一种可持续的、环保的材料，以减少汽车的污染。现有用于减少污染的技术是一种催化转化器，它含有昂贵的稀有金属，并且在发动机启动时性能不佳。气凝胶是一种特殊的轻质材料，具有许多特性，使其成为催化转化器的一个有吸引力的补充。气凝胶催化转化器将为减少汽车污染提供一种经济上有吸引力和可持续的方法，从而对国家的经济和环境产生重大的积极影响。该项目将开发新的气凝胶来实现这些目标。此外，该项目将开发一个研究/创业实习，让学生（包括那些传统上代表性不足的群体）参与开发创业理念，并学习如何将通过基础研究开发的技术推向市场。这种本科课程的新模式将为学生提供大量的创业经验，而正是在这种培训可能产生最大影响的时候：在进入研究生院或STEM劳动力之前。拟议中的项目将开发和测试新的气凝胶催化剂，用于开发减少汽车污染的先进技术。催化转化器目前面临的主要技术挑战之一是它无法在冷启动条件下减少或消除排放。气凝胶具有许多特性（高温稳定性、大表面积、低质量和可调化学性质），使其成为一种可行的替代技术，并且已被证明在减少废气污染方面具有积极作用。通过调整其化学性质，气凝胶可以具有催化活性，并能有效地促进废气污染物的转化。拟议的项目将解决与开发这种潜在的变革性替代技术相关的几个技术挑战，以减少冷启动排放：(1)开发具有替代化学物质的催化活性气凝胶，以改善活化特性；(2)证明这些材料的高温生存能力(3)研究催化活性气凝胶降低热惯性的潜力；(4)将气凝胶加入常规的水洗涂层方法中；(5)将气凝胶集成到催化转化器原型中；(6)为本科STEM学生开发创新和创业方面的广泛培训和领导力发展的可转移模式。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
