项目摘要

1067800PI: WeimerThere is a need and opportunity to develop controlled pore diameter/porosity/thickness ultra-thin microporous/mesoporous films on particles. Applications include corrosion protective coatings, gas storage, and catalyst encapsulation for controlling reaction selectivity and for reducing sintering, thus maintaining catalytic activity. Successful completion of this research will result in a better understanding of the fabrication of porous oxide films with controllable thickness and pore size and the design of catalysts that are more resistant to sintering and have higher selectivity. The pore size of the films can be controlled by selection of the organic component in the molecular layer deposited (MLD) hybrid polymer films and the method for removing the organic component, forming pores in the MLD films. Variables to be investigated for the formation of porous films include the effect of MLD precursor chemistry, MLD reaction temperatures, and methods for the formation of porous structures. Because the oxide layers are so thin (1-5 nm), they are not expected to significantly decrease the rate of the desired reaction. Thus, the specific goal is to increase selectivity and lifetime with essentially no loss in rate of the desired reactions. The catalytic properties of supported catalysts could then be designed by selecting the oxide layer thickness, the size of the oxide pores, and the composition of the oxide. The catalysts will be evaluated using oxidation reactions. ALD NanoSolutions, Inc. will provide access to and support for students using a quartz crystal microbalance (QCM) to investigate new MLD chemistries. Additionally, baseline supported Pt/silica gel catalyst to be used for the film and reaction studies will be provided by ALD NanoSolutions, Inc. Broader Significance and Importance: The ability to prepare highly porous oxide films with controllable thickness and pore size would make generational gains in the preparation of thermally stable catalyst nanoparticles. Since sintering and poisoning are two of the main deactivation mechanisms for catalysts, decreasing the rates of these processes would decrease the amount of precious metals required in catalysts, increase lifetimes and ultimately improve the economics of many processes. The proposed approach has great potential for application in a large number of catalytic processes. Other significant areas for application include controlling the selectivity of membrane separations for sensors and filtration devices, providing a high surface area moiety for functionalization for H2 gas storage or the attachment of active agents for drug delivery, among others. The broader educational application of this proposed research plan is the contribution that is anticipated through the dissemination of results to the particle technology and catalysis communities. This research is not only an excellent vehicle for training a Ph.D. students on an industrially significant project, but is an excellent opportunity to impact undergraduate students and peripheral K-12 outreach. Both graduate and undergraduate students will have opportunities to present their research results at national meetings. From a commercial perspective, ALD NanoSolutions, Inc. has agreed to test market the optimized stabilized Pt catalyst with their potential customers.
1067800PI:Weimer 有必要和机会开发颗粒上受控孔径/孔隙率/厚度的超薄微孔/介孔薄膜。 应用包括防腐涂层、气体储存和催化剂封装,用于控制反应选择性和减少烧结,从而保持催化活性。 这项研究的成功完成将有助于更好地理解厚度和孔径可控的多孔氧化物薄膜的制造以及更耐烧结和更高选择性的催化剂的设计。膜的孔径可以通过选择分子层沉积(MLD)杂化聚合物膜中的有机成分以及去除有机成分、在MLD膜中形成孔的方法来控制。多孔薄膜形成需要研究的变量包括 MLD 前驱体化学的影响、MLD 反应温度和多孔结构的形成方法。由于氧化层非常薄(1-5 nm),因此预计它们不会显着降低所需反应的速率。因此,具体目标是提高选择性和寿命,同时基本上不损失所需反应的速率。然后可以通过选择氧化物层厚度、氧化物孔的尺寸和氧化物的组成来设计负载型催化剂的催化性能。将使用氧化反应来评估催化剂。 ALD NanoSolutions, Inc. 将为使用石英晶体微天平 (QCM) 研究新 MLD 化学物质的学生提供访问和支持。 此外,用于薄膜和反应研究的基线负载 Pt/硅胶催化剂将由 ALD NanoSolutions, Inc. 提供。 更广泛的意义和重要性:制备厚度和孔径可控的高度多孔氧化物薄膜的能力将使热稳定催化剂纳米颗粒的制备取得世代性的进步。由于烧结和中毒是催化剂的两种主要失活机制,因此降低这些过程的速率将减少催化剂所需的贵金属量,延长使用寿命并最终提高许多过程的经济性。该方法在大量催化过程中具有巨大的应用潜力。其他重要的应用领域包括控制传感器和过滤装置的膜分离的选择性、为氢气存储的功能化提供高表面积部分或为药物输送连接活性剂等。该拟议研究计划的更广泛的教育应用是通过将结果传播到粒子技术和催化界而预期做出的贡献。这项研究不仅是培养博士的绝佳工具。学生参与一个具有工业意义的项目,但这是一个影响本科生和外围 K-12 外展的绝佳机会。研究生和本科生都有机会在全国会议上展示他们的研究成果。 从商业角度来看,ALD NanoSolutions, Inc. 已同意与其潜在客户一起测试优化的稳定 Pt 催化剂。
