This research project, supported in the Analytical and Surface Chemistry Program, addresses the development of an effective methodology for the synthesis and characterization of ordered mesoporous silica materials. Surface functionalization of these materials, determination of type, bonding density, and uniformity of surface coverage of the surface functionalities, and the determination of the size of pore windows in these materials are the main objectives of this research. Characterization methods developed in this research have applicability to a broad range of high surface area materials, and are not limited to the mesoporous silica materials that are the focus of Professor Mietek Jaroniec's research at Kent State University.The development of methodologies for the determination of surface coverage and type of modifier is the focus of this research project supported in the Analytical and Surface Chemistry Program. Synthesis of mesoporous modified silica materials, followed by characterization using the methodologies developed here, is the goal of the work. These methodologies will have wide applicability beyond the modified silicas that form the main topic of research.

该研究项目，在分析和表面化学计划的支持下，解决了有序介孔二氧化硅材料的合成和表征的有效方法的发展。 这些材料的表面功能化，确定类型，键合密度和均匀性的表面覆盖的表面功能，并确定在这些材料中的孔窗口的大小是本研究的主要目标。 在这项研究中开发的表征方法具有广泛的高表面积材料的适用性，并不局限于Mietek Jaroniec教授在肯特州立大学的研究重点的介孔二氧化硅材料。表面覆盖率和类型的改性剂的测定方法的发展是本研究项目的重点支持的分析和表面化学计划。 合成介孔改性二氧化硅材料，然后使用这里开发的方法进行表征，是工作的目标。 这些方法将具有广泛的适用性，超出了改性二氧化硅，形成的主要研究课题。
