Surface and Structural Studies of Noble Metal Catalysts with Ceria-Based Supports

控制汽车发动机的废气排放在加拿大和世界其他地方都很重要。随着有关道路发动机的法规越来越严格，催化行业对更多地了解有助于提高用于废气净化的燃烧催化剂的效率的现象感兴趣。为了制造能够满足这些需求的催化剂，并改进现有的系统，需要更好的表征方法来测试这些系统，以及微调支撑贵金属催化剂的能力。由于氧迁移率是支撑催化剂正常工作的关键因素之一，因此该参数将通过表面和结构表征方法进行量化。所获得的系统的催化活性与上述性质的相关性将使工程新系统成为可能，这可以导致所需的废气流净化水平。**这个拟议的研究项目涉及贵金属催化系统支撑体的合成，以研究可用于更好地评估和设计适合现代废气净化系统的催化剂的方法，这些催化剂将符合当前加拿大的排放标准。该项目旨在发展DCL国际公司（DCL）和谢里丹学院之间的新伙伴关系，项目团队建议对获得的系统的特性和活动进行初步测试。随着更先进的设备的到位，支撑和完整的催化系统将由DCL进行测试，DCL也旨在应用从项目中获得的知识来提高目前提供的产品

Controlling exhaust emissions from automotive engines is important in Canada and the rest of the world. With the increasingly stringent regulations regarding on-road engines, the catalytic industry is interested in gaining more understanding of phenomena that can help increase the efficiency of combustion catalysts used for exhaust purification. To manufacture catalysts that can meet these demands, as well as improve already existing systems, better characterisation methods for testing these systems and the ability to fine tune supported noble metal catalysts are needed. Since oxygen mobility is one of the key factors for the proper functioning of caria-supported catalysts, this parameter will be quantified with surface and structural characterisation methods. The correlation of the catalytic activity of the obtained systems with the aforementioned properties will enable engineering new systems, which can lead to the desired levels of exhaust stream purification.** This proposed research project involves the synthesis of supports for noble metal catalytic systems to investigate the methods that can be used to better assess and engineer suitable catalysts for modern exhaust purification systems, which will meet current Canadian emission standards. The project aims to develop a new partnership between DCL International Inc. (DCL) and Sheridan College, where the project team proposes to conduct initial testing of properties and activity of the obtained systems. With more advanced equipment in place, the supports and complete catalytic systems will then be tested by DCL, which also aims to apply the knowledge gained from the project to enhance the products currently offered.**
