项目摘要
1067803DatyeThe treatment of CO and hydrocarbons in the exhaust of lean-burn engines continues as a challenge impacting the deployment of these improved efficiency automobiles. This will likely be aggravated as the use of biodiesel and other alternative fuel components enter the pool. Low temperature after-treatment catalysts based on noble metals are still the best choice for dealing with the pollutants. The economics of the situation dictate that more active and stable catalysts, particularly those using less noble metal contents, are highly desirable R and D targets. This GOALI proposal combines efforts from 2 universities and an automotive industry lab to address this problem. Based on observations that Palladium will prevent the emission of volatile Platinum oxides made at the University of New Mexico, and that a physical mixture of these two monometallic catalysts will give results of bimetallic catalytic nature made at the General Motors Labs, a team of Prof. Abhaya Datye from the University of New Mexico, Prof. Boris Kiefer from New Mexico State University, and Scientists Michael Balogh, Chang Kim and Wei Li from General Motors Laboratory are collaborating to understand the synergistic effects of palladium for platinum stability and for the ability to self-assemble a bimetallic catalyst from independent particles. A wide variety of ex situ and in situ techniques will be coupled with state-of-the-art computational DFT simulation to elucidate the answers to the questions that arise from these observations. The fundamental understanding developed through characterization and computation will potentially open a window on less-costly catalysts for low temperature oxidations which may extend beyond the pollutants Carbon monoxide and hydrocarbons. The broader impact is apparent in terms of this science ultimately leading to potential cost reduction in post engine burn catalytic treatments. Effective lowering of the cost for pollution treatments allows the attainment of better quality air overall. There seems to be an effective interaction between the universities and GM Laboratory scientists that will optimize the outcome and utility of the results. The students involved will be exposed to the industrial environment, the academic environment, and the impact of the environment on the technologies that humans employ. They will be well-rounded after participation in this program.
贫燃发动机排气中CO和碳氢化合物的处理仍然是一个挑战,影响着这些提高效率的汽车的部署。随着生物柴油和其他替代燃料成分的使用进入池中,这种情况可能会加剧。基于贵金属的低温后处理催化剂仍然是处理污染物的最佳选择。目前的经济形势决定了更活跃、更稳定的催化剂,尤其是那些贵金属含量较低的催化剂,是非常可取的研发目标。这项目标提案结合了两所大学和一个汽车工业实验室的努力来解决这个问题。基于钯将防止新墨西哥大学生产的挥发性铂氧化物的排放,以及这两种单金属催化剂的物理混合物将产生通用汽车实验室制造的双金属催化性质的结果,新墨西哥大学的Abhaya Datye教授、新墨西哥州立大学的Boris Kiefer教授以及通用汽车实验室的科学家Michael Balogh、Chang Kim和魏丽正在合作了解钯对铂稳定性和从独立颗粒自组装双金属催化剂的能力的协同作用。各种各样的非原位和原位技术将与最先进的计算DFT模拟相结合,以阐明这些观测所产生的问题的答案。通过表征和计算而形成的基本认识可能会打开一个窗口,了解成本较低的低温氧化催化剂,这些催化剂可能超出污染物、一氧化碳和碳氢化合物的范围。就这一科学而言,更广泛的影响是显而易见的,最终导致发动机燃烧后催化处理的潜在成本降低。有效降低污染治理成本,可以实现更好的整体空气质量。大学和转基因实验室的科学家之间似乎有一种有效的互动,这将优化结果和结果的效用。参与其中的学生将接触到工业环境、学术环境以及环境对人类使用的技术的影响。参加这个项目后,他们将全面发展。
