中文摘要
宾夕法尼亚州立大学的 M. Albert Vannice 教授与东北大学的 Baker 教授和博士合作。孟山都公司的 Friedman 和 Ebner 将研究碳(活性、石墨纤维和金刚石形式)负载的双金属 Cu(Pt、Pd、Rh)颗粒的制备和表征。 他们将确定醇气相和液相脱氢为烯烃的动力学和催化机制,这些反应与孟山都公司使用的工业流程相关。 这项研究的一个广泛动机是可能替代这些过程中使用的对环境有害的亚铬酸铜催化剂。 对环境也很重要的是开发高选择性、无浪费的工艺。 在基础层面上,迫切需要更好地了解双金属纳米粒子的特性。 特别是对于醇脱氢,催化性能对负载在各种类型碳基底上的双金属纳米颗粒的组成、结构、固相、形态、电子态和分散度的依赖性知之甚少或了解甚少。 尚未研究气相和液相催化行为的差异。 博士。贝克和范尼斯将准备新型催化剂。 Vannice 博士将通过 XRD、IR、TEM 和化学吸附来表征颗粒尺寸和表面功能组成,而 Baker 博士将通过可控气氛电子显微镜和 TEM 提供双金属颗粒的形态和化学状态。 博士。 Friendman Ebner 将通过 XPS 和 EXAFS 提供额外的化学成分和结构信息。 Vannice 博士将为正丁醇、3-甲基丁醇、巴豆醇和异丙醇的气相脱氢提供催化动力学测量,而孟山都将为液相反应进行类似的测定。
英文摘要
Professor M. Albert Vannice at Penn Sate University, in collaboration with Prof. Baker at Northeastern University, and Drs. Friedman and Ebner at Monsanto Corporation, will study the preparation and characterization of bimetallic Cu- (Pt, Pd, Rh) particles supported on carbon (in the activated, graphitic fiber, and diamond forms). They will determine the kinetics and catalytic mechanisms of vapor-phase and liquid-phase dehydrogenation of alcohols to alkenes, reactions that are relevant to industrial processes utilized by Monsanto. A broad motivation for the research is the potential replacement of environmentally hazardous copper chromite catalysts used in those processes. Also environmentally important is the development of highly selective, wasteless processes. At the fundamental level there is outstanding need for better understanding of bimetallic nanoparticles properties. In particular for alcohol dehydrogenation, the catalytic property dependence on composition, structure, solid phases, morphology, electronic state, and dispersion of bimetallic nanoparticles supported on various types carbon substrates is poorly known or little understood. Differences of behavior for vapor and liquid phase catalysis have not been investigated. Drs. Baker and Vannice will prepare the novel catalysts. Dr. Vannice will characterize particle size and surface-functional composition by XRD, IR, TEM and chemisorption while Dr. Baker will provide morphology and chemical state of the bimetallic particles by Controlled Atmosphere Electron Microscopy and TEM. Drs. Friendman Ebner will provide additional chemical composition and structural information by XPS and EXAFS. Dr. Vannice will provide catalytic kinetics measurements for the vapor-phase dehydrogenation of n-butanol, 3-methylbutanol, crotyl alcohol and isopropanol, while Monsanto will do similar determinations for the liquid-phase reactions.
