Surface Chemistry of Silicon Oxide Nanostructures in Molecule Corrals

这项研究项目是由特拉华大学化学系的Beebe教授和Teplyakov教授合作完成的，该项目使用石墨表面的纳米坑来模板硅氧化物纳米结构的生长。这些“分子围栏”模板可以在石墨衬底上以受控的方式形成，并被用来可控地合成一系列二氧化硅纳米颗粒，然后对其表面修饰化学进行系统的研究。来自这项工作的信息有助于设计合成纳米材料的过程化学，该材料在电子设备和传感器系统中具有广阔的应用前景。在分析和表面化学项目的支持下，特拉华大学的Beebe教授和Teplyakov教授正在研究可控制地合成各种尺寸、形状和尺寸分布的二氧化硅纳米颗粒的方法。利用毕比实验室开发的“分子畜栏”作为模板，可以生产出广泛的可控纳米材料。然后在这项研究中对这些二氧化硅纳米材料的表面化学进行了检测。

AbstractCHE-0415979Beebe/DelawareThis research project, carried out in collaboration between Professors Beebe and Teplyakov in the Department of Chemistry at the University of Delaware, uses nanopits in graphite surfaces to template the growth of silicon oxide nanostructures. These "molecule corral" templates can be formed in a controlled fashion on the graphite substrate, and are used to controllably synthesize a range of silicon oxide nanoparticles, whose surface modification chemistry is then systematically studied. Information from this work helps to design process chemistries for the synthesis of nanomaterials with promising applications in electronic devices and sensor systems. With the support of the Analytical and Surface Chemistry Program, Professors Beebe and Teplyakov at the University of Delaware are examining methods for controllably synthesizing silicon oxide nanoparticles of various sizes, shapes, and size distributions. Using "molecular corrals" developed in Beebe's laboratory as templates, a wide range of controlled nanomaterials can be produced. The surface chemistry of these silica nanomaterials is then examined in this research.
