CAREER: Synthesis and Analysis of Mixed-Phase Microporous/Mesoporous Materials and Implementation of Distance Learning Techniques

佛蒙特大学授予克里斯托弗·C·兰德里的这一职业奖项得到了化学部先进材料项目的支持。研究了混合相微孔/介孔硅酸盐和铝硅酸盐的合成、表征及其催化和层析行为。在有机胶束模板存在下，在水溶液中和室温下，通过硅酸盐源的初始聚合制备混合相，形成弱组织的介孔材料。该材料随后将在结构导向剂(通常为四丙基铵阳离子)存在的情况下加热，以形成微孔材料。不完全退火可制得混合介孔/微孔复合材料。结构，作为反应变量的函数将被探索。用X射线衍射仪、核磁共振、红外光谱、扫描电子显微镜、透射电子显微镜和孔隙率测量法对混合相进行了表征。这些材料将作为烯烃异构化的催化剂和色谱支撑进行评估。职业教育计划将重点放在将材料化学纳入研究生和本科课程。还将开发材料化学课程，并利用当地教师和工业科学家作为资源。课程和专题讲座将通过大学的远程学习网络以电子方式传播，使偏远地区的研究生和工业科学家都能获得高级学位的学分。该计划将包括兰德里教授的研究和其他当地工业项目的例子，预计将促进产学研究伙伴关系。

This CAREER award to Christopher C. Landry at the University of Vermont is supported by the Advanced Materials Program in the Chemistry Division. The research deals with the synthesis, characterization and catalytic and chromatographic behavior of mixed phase microporous/mesoporous silicates and aluminosilicates. The mixed phases will be prepared by initial polymerization of a silicate source in the presence of an organic micellar template in aqueous solution and room temperature to form a weakly-organized mesoporous material. This material will be subsequently heated in the presence of a structure-directing agent, typically tetrapropyl ammonium cation, to form a microporous material. Incomplete annealing will produce mixed mesoporous/microporous composites. Structure, as a function of reaction variables will be explored. XRD, NMR, IR, SEM, TEM and porosimetry will be employed to characterize the mixed phases. The materials will be evaluated as catalysts for olefin isomerization and as chromatographic supports.The CAREER educational plan will focus on the inclusion of Materials Chemistry into both graduate and undergraduate curricula. Courses in Materials Chemistry will be developed which will also utilize local faculty and industrial scientists as resources. Classes and special lectures will be electronically disseminated through the University's Distance Learning Network, permitting both graduate students and industrial scientists at remote locations to earn credit towards advanced degrees. The program will include examples from Prof. Landry's research and other local industrial projects and is expected to stimulate industrial-academic research partnerships.
