This research project investigates the preparation and properties of ligand capped transition metal oxide nanoparticles. With the support of the Analytical and Surface Chemistry Program, Professor Daniel Buttry and Professor Jeffery Yarger in the Department of Chemistry at the University of Wyoming use a variety of approaches, including chemical vapor deposition and reverse-micelle techniques to synthesize nanometer scale particles of manganese oxide, titanium oxide, nickel oxide, vanadium oxide and tungsten oxide. The particles are capped with carboxyalkylphosphonates with binding via the phosphonate groups and assembled into three dimensional structures using divalent metal ions as linking agents at the carboxylate groups. The three dimensional arrays are studied using electrochemistry and solid-state nuclear magnetic resonance methods. This project is developing materials that have application in the field of batteries and energy storage. It is expanding available nanometer scale materials to include more oxides and is further developing solid state nuclear magnetic resonance techniques as a means to characterize nanoscale materials. Results have broad impact in areas related to energy storage and inorganic materials synthesis.

本研究计画探讨配位体包覆的过渡金属氧化物奈米粒子的制备与性质。 在分析和表面化学项目的支持下，怀俄明州大学化学系的丹尼尔·巴特里教授和杰弗里·雅格教授使用各种方法，包括化学气相沉积和反胶束技术，合成氧化锰、氧化钛、氧化镍、氧化钒和氧化钨的纳米级颗粒。 该颗粒用羧基烷基膦酸酯封端，通过膦酸酯基团结合，并使用二价金属离子作为羧酸酯基团处的连接剂组装成三维结构。 利用电化学和固态核磁共振方法研究了三维阵列。 该项目正在开发可应用于电池和储能领域的材料。 它正在扩大现有的纳米级材料，以包括更多的氧化物，并正在进一步开发固态核磁共振技术，作为表征纳米级材料的一种手段。 研究结果在储能和无机材料合成相关领域具有广泛的影响。
