Abstract#1151098P.I.: Jeffrey RimerTailoring crystallization of zeolites with predictable structural outcomes is a challenge in zeolite catalyst design, wherein few synthetic approaches are amenable to systematic and precise manipulation of material properties. Developing facile, inexpensive routes to precisely control crystal habit (i.e. morphology and orientation) can address design limitations that often marginalize catalyst performance and can hinder their commercial viability. Prof. Jeffrey Rimer of the University of Houston proposes in his CAREER award study to develop a rational design strategy for improving the mass transport properties of zeolite catalysts, notably a reduction in the internal pore diffusion path length and an increase in the exterior pore surface area, which are known to markedly improve activity and stability. With this award, Rimer will leverage research thrusts in crystal engineering and surface science to tailor zeolite crystallization at an interfacial level, using a bio-inspired approach to tune crystal habit and surface architecture, and ultimately to test catalyst activity as a function of these variables. This design approach mimics crystallization in nature by using modifiers with molecular recognition for binding to specific surfaces and mediating step growth on crystal faces. Initiatives will focus on reactions of model compounds with a long-term trajectory of establishing a comprehensive platform to design, model, and test zeolites for alternative energy applications.This award will be used to strengthen outreach initiatives at the K-12, undergraduate, and graduate levels to promote engineering education and research. Rimer has partnered with KIPP Houston High School (a minority institution ranked 16th in national college readiness) to establish a dynamic program for student and teacher (NSF-RET) research at the University of Houston, guest lectures on engineering topics to KIPP AP Chemistry students, lesson plans that integrate results of Rimer's research, and an annual seminar to promote increased interest in STEM.

摘要＃1151098P.I。：具有可预测的结构结果的沸石结晶的杰弗里·里米特尾能是沸石催化剂设计中的挑战，其中很少有合成方法能够系统地进行系统的和精确的材料特性操纵。开发精确控制晶体习惯（即形态和方向）的便捷，廉价的途径可以解决设计局限性，这些局限性通常会使催化剂的性能边缘化，并可能阻碍其商业可行性。休斯顿大学的杰弗里·里默（Jeffrey Rimer）教授在其职业奖项研究中提出，制定了一种合理的设计策略，以改善沸石催化剂的质量运输特性，尤其是内部孔隙扩散路径长度的减小和外部孔隙表面积的增加，这些孔隙表面积显着提高了活动和稳定性。有了这个奖项，Rimer将利用以生物启发的方法来调整晶体习惯和表面体系结构，利用晶体工程和表面科学的研究推力在界面上量身定制沸石结晶，并最终将催化剂活性作为这些变量的函数。这种设计方法通过使用具有分子识别的修饰符与特定表面结合并介导晶体面上的步骤生长来模仿自然界中的结晶。倡议将重点关注模型化合物的反应，其长期轨迹建立了用于替代能源应用的设计，模型和测试沸石的全面平台。该奖项将用于加强K-12的外展计划，本科生和研究生水平，以促进工程教育和研究。 Rimer与Kipp Houston High School（少数族裔机构在全国大学准备中排名第16位），在休斯顿大学为学生和教师（NSF-RET）研究建立了动态​​计划，有关Kipp AP Chemistry学生的工程主题的客座讲座，从而使Rimer Research的成绩以及促进Seminar的年度促进seminar兴趣的成绩。
