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.**

控制汽车发动机的尾气排放在加拿大和世界其他地区都很重要。随着道路发动机法规的日益严格，催化行业有兴趣更多地了解有助于提高用于尾气净化的燃烧催化剂效率的现象。为了制造能够满足这些需求的催化剂，以及改进现有的系统，需要更好的表征方法来测试这些系统，并需要有能力微调负载型贵金属催化剂。由于氧的迁移率是载体催化剂正常运行的关键因素之一，这一参数将用表面和结构表征方法来量化。所获得的系统的催化活性与上述特性的相关性将使设计新系统成为可能，这将导致所需的废气净化水平。**这项拟议的研究项目涉及贵金属催化系统载体的合成，以研究可用于更好地评估和设计适用于现代废气净化系统的催化剂的方法，这些催化剂将满足加拿大当前的排放标准。该项目旨在发展DCL国际公司(DCL)和谢里登学院之间的新伙伴关系，在那里，项目组提议对所获得的系统的性能和活动进行初步测试。随着更先进的设备就位，DCL将对载体和完整的催化系统进行测试，该公司还旨在应用从该项目中获得的知识来改进目前提供的产品。**
