The broader impact/commercial potential of this Partnerships for Innovation - Research Partnerships (PFI-RP) project are manyfold. First, if successful, it will provide a new class of materials to meet needs for diesel emission, impacting the transportation industry. The global market of heavy duty diesel catalysts for on-road trucks is projected to reach $2.6 billion in 2020. The product and technology are expected to help the US sustain its leadership in the field of low-temperature emission control, supporting a cleaner environment, through reduced use of certain metals, and enhancing economic competitiveness through export opportunities. The integration of research and product development demonstrated in this university-industry partnership program will form an important model and foundation to help pursue a sustained industrial-university research collaboration ecosystem. The broad application of this new technology is expected to produce new jobs and significant economic impact. An important outcome of this partnership project is the intensive training of students through the organic integration of academic research, technology transfer, and entrepreneurship. The team plans to use this unique partnership model to build a pipeline to demonstrate to student and postdoctoral researchers, especially women and under-represented groups, how frontier research can be directly transferred to industry for commercialization.The proposed project intends to develop a high-efficiency, durable, and low-cost multifunctional adsorbers for low temperature and cold-start diesel emission control. Such multifunctional adsorbers combine the functions of low temperature nanoarray diesel oxidation catalyst (DOC) and low temperature adsorbers (LTA), forming a total solution at temperatures as low as 100 degrees Celsius. However, the DOCs that can work efficiently at temperatures below 200 degrees Celsius are not available in the current market, and are in urgent demand. In this project, surrounding the proposed university-industry partnership, the team will integrate the nanoarray DOCs with LTAs as a new class of multifunctional adsorbers. Scalable continuous hydrothermal and other processes at temperatures below 200 degrees Celsius will be used to enable the cost-effective fabrication of large scale stable multilayer adsorbers. The full-size adsorbers will be processed and validated for emission control through both lab and simulated field tests, with high catalytic activity at low temperature, robustness, and low materials usage.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.

这一创新-研究伙伴关系（PFI-RP）项目的广泛影响/商业潜力是多方面的。首先，如果成功，它将提供一种新的材料来满足柴油排放的需求，从而影响运输行业。 预计到2020年，用于公路卡车的重型柴油催化剂的全球市场将达到26亿美元。该产品和技术有望帮助美国保持其在低温排放控制领域的领导地位，通过减少某些金属的使用来支持更清洁的环境，并通过出口机会提高经济竞争力。这项大学与产业合作计划所展示的研究和产品开发的整合将成为一个重要的模式和基础，有助于实现可持续的工业与大学研究合作生态系统。这项新技术的广泛应用预计将产生新的就业机会和重大的经济影响。该合作项目的一个重要成果是通过学术研究、技术转让和创业精神的有机结合对学生进行强化培训。该团队计划利用这种独特的合作模式，建立一个管道，向学生和博士后研究人员，特别是女性和代表性不足的群体，展示如何将前沿研究直接转移到工业中进行商业化。拟议项目旨在开发一种高效，耐用，低成本的多功能吸附器，用于低温和冷启动柴油排放控制。这种多功能吸附器联合收割机结合了低温纳米阵列柴油机氧化催化剂（DOC）和低温吸附器（LTA）的功能，在低至100摄氏度的温度下形成总溶液。然而，能够在200摄氏度以下的温度下高效工作的DOC在当前市场上是不可用的，并且是迫切需要的。在这个项目中，围绕拟议的大学-工业合作伙伴关系，该团队将把纳米阵列DOC与LTA集成为一类新的多功能吸附器。将使用温度低于200摄氏度的可扩展连续水热和其他工艺，以实现大规模稳定多层吸附器的成本效益制造。全尺寸吸附器将通过实验室和模拟现场测试进行处理和验证，用于排放控制，具有低温下的高催化活性，坚固耐用，材料使用量低。该奖项反映了NSF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。
