Proposal Title: GOALI: High Throughput Activity and in-situ FTIR and EXAFS Studies of the Effect of Sulfur on Noble Metal Supported Oxidation CatalystsProposal Number: CTS-0138070Principal Investigator: Eduardo WolfInstitution: Notre Dame UniversityThe objective of this proposal is to investigate the effects of sulfur on the state of the surface of supported platinum, palladium, and rhodium catalysts and to develop structure-activity correlations for these catalysts during oxidation reaction. The approach is to conduct a comprehensive study on the effect of sulfur poisoning on model oxidation reactions by combining kinetic measurements, catalyst characterizations, and microkinetic and Monte Carlo simulations of the experimental results. High throughput catalyst evaluations will be used to ascertain the effect of sulfur on carbon monoxide, propane, and proplyene oxidation on Pt, Pd, and Rh on a variety of oxide supports. An array of catalysts will be used to identify the major trends in activity caused by sulfur poisoning of the catalysts' surface. Selected samples will be studied using a variety of surface analytical techniques such as EXAFS and FTIR. An industrial collaborator brings expertise in surface science and catalyst preparation techniques. The results of this study may be useful in developing more sulfur-tolerant catalysts in automobile exhaust applications and for fuel cells.

建议标题：GALI：高通量活性和原位FTIR和EXAFS研究硫对贵金属负载氧化催化剂的影响建议编号：CTS-0138070主要研究员：爱德华多·沃尔夫研究所：圣母大学本建议的目的是研究硫对负载铂、钯和铑催化剂表面状态的影响，并建立这些催化剂在氧化反应中的结构-活性关系。该方法采用动力学测量、催化剂表征、微观动力学和蒙特卡罗模拟相结合的方法，对硫中毒对模型氧化反应的影响进行了全面的研究。高通量的催化剂评估将被用来确定硫对一氧化碳、丙烷和丙烯在铂、钯和Rh上在各种氧化物载体上氧化的影响。将使用一系列催化剂来确定催化剂表面硫中毒造成的主要活性趋势。选定的样品将使用各种表面分析技术进行研究，如EXAFS和FTIR。工业合作者带来了表面科学和催化剂制备技术方面的专业知识。这项研究的结果可能有助于开发更耐硫的汽车尾气催化剂和燃料电池。
