04369895DavisThis three-year U.S.-France cooperative research project between Mark E. Davis of the California Institute of Technology and Veronique Dufaud of the Laboratoire de Chimie, Ecole Normale Superieure in Lyon, France focuses on preparing solid catalysts of structural uniformity. The proposed project is an extension of the U.S. and French investigators previous work on synthesis and catalytic behavior of mesoporous silicas containing positioned sulfonic acid groups. Intellectual MeritThe objective is to investigate structure-property relationships of organic-inorganic hybrid materials where the inorganic component provides surface area and porosity and the organic groups are organized on its surface. Results from zeolite-based catalysts suggest strong correlation between nanoscopic/mesoscopic uniformity and high selectivity. The investigators propose to create structural uniformity that contains: (1) multiple organic groups in precise arrangement in order to study the effects of cooperativity; and (2) multiple organic group types to catalyze multistep reaction pathways. Broader ImpactsThe proposal adds an international dimension to an active NSF - NIRT (Nanoscale Science and Engineering Independent Research Team) research award on zeolite nanoparticles. The U.S. investigator is expert in synthesis and characterization of organic-inorganic hybrid materials and has broader experience in catalysis. This is complemented by French expertise in synthesis and surface organo metallic chemistry. Their efforts will advance understanding and creation of new catalysts. Catalytic activity is the basis for the chemistry industry. The project gives a U.S. postdoctoral research and graduate student an international experience via research immersion at a leading French institution. The project advances the student's international research skills and assists with developing international connections for future.

04369895戴维斯这三年美国-法国合作研究项目马克E。加州理工学院的Davis和法国里昂的巴黎师范大学化学系的Veronique Dufaud专注于制备结构均匀的固体催化剂。 拟议的项目是美国和法国研究人员先前关于含有定位磺酸基团的介孔二氧化硅的合成和催化行为的工作的延伸。其目的是研究有机-无机杂化材料的结构-性能关系，其中无机组分提供表面积和孔隙率，有机基团在其表面上组织。沸石基催化剂的结果表明，纳米/介观均匀性和高选择性之间有很强的相关性。 研究人员建议创建结构均匀性，其中包含：（1）精确排列的多个有机基团，以研究协同效应;（2）多种有机基团类型，以催化多步反应途径。更广泛的影响该提案增加了一个积极的NSF - NIRT（纳米科学与工程独立研究小组）的沸石纳米粒子研究奖的国际层面。 美国研究人员是有机-无机杂化材料合成和表征方面的专家，在催化方面拥有更广泛的经验。 法国在合成和表面有机金属化学方面的专业知识对此进行了补充。他们的努力将促进对新催化剂的理解和创造。 催化活性是化学工业的基础。 该项目通过在法国领先机构进行研究沉浸，为美国博士后研究和研究生提供国际体验。该项目提高了学生的国际研究技能，并协助发展未来的国际联系。
