摘要项目名称:单层氧化物催化剂催化氧化机理的模型研究项目编号:cts -0000283项目负责人:Robert madix机构:斯坦福大学该项目的目标是进一步了解混合金属氧化物这一重要的催化材料的生长和化学活性。模型单晶氧化物表面将被用作支撑,支撑氧化物将被制造和研究使用一些表面科学工具。特别地,钒负载在钛和氧化铝单晶表面的亚单层到单层覆盖将被研究。支持钒将使用化学气相沉积和浸泡在水溶液中生长。用扫描隧道显微镜研究了负载氧化物的生长形态和结构。电子结构将通过光电子能谱和电子能量损失能谱进行研究。相关的表面反应性将通过温度编程方法和稳态反应技术进行检查。甲醇氧化和丁烯还原将作为试验反应。大量的商业非均相催化剂都是基于负载型钒,本研究对钒和其他负载型氧化物催化剂的制备和开发具有指导意义。
英文摘要
AbstractProposal Title: Model Studies of the Mechanism of Catalytic Oxidation by Monolayer Oxide CatalystsProposal Number: CTS-0000283Principal Investigator: Robert MadixInstitution: Stanford UniversityThe goal of this project is to further fundamental understanding of the growth and chemical activity of mixed metal oxides, which are important catalytic materials. Model single crystal oxide surfaces will be used as supports, and supported oxide will be fabricated and studied using a number of surface science tools. In particular, vanadia supported on titania and alumina single crystal surfaces at submonolayer to monolayer coverages will be studied. Supported vanadia will be grown using chemical vapor deposition and immersion in aqueous solution. The growth morphology and structure of the supported oxide will be studied by scanning tunneling microscopy. The electronic structure will be studied by photoelectron and electron energy loss spectroscopy. Related surface reactivity will be examined by both temperature programmed methods and by steady state reaction techniques. Methanol oxidation and butene reduction will be used as test reactions. A large number of commercial heterogeneous catalysts are based on supported vanadia species, and this work has the potential to guide the preparation and development of vanadia and other supported oxide catalysts.
