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

这个职业奖给克里斯托弗·C。Landry在佛蒙特大学的研究得到了化学系先进材料项目的支持。本论文研究了微孔/介孔混合相硅酸盐和铝硅酸盐的合成、表征、催化性能和色谱性能。混合相将通过硅酸盐源在有机胶束模板存在下在水溶液中和室温下的初始聚合来制备，以形成弱组织的介孔材料。随后将该材料在结构导向剂（通常为四丙基铵阳离子）存在下加热以形成微孔材料。 不完全退火将产生混合的介孔/微孔复合材料。结构，作为反应变量的函数将被探索。采用XRD、NMR、IR、SEM、TEM和孔隙率仪对混合相进行表征。这些材料将作为烯烃异构化的催化剂和色谱载体进行评估。CAREER教育计划将侧重于将材料化学纳入研究生和本科生课程。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。 课程和特别讲座将通过大学的远距离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攻读高级学位的学分。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，预计将刺激工业-学术研究伙伴关系。

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.
