Professor Royce W. Murray of the University of North Carolina at Chapel Hill is supported by the Chemical Catalysis Program in the Division of Chemistry to study the electrocatalytic oxidation of water by solution-dispersed iridium oxide nanoparticles, and to enhance the analytical capabilities for determining the composition and properties of very small nanoparticles. Specifically, the research plan seeks a better understanding of the mechanisms by which un-supported and supported iridium oxide nanoparticles are effective as water oxidation catalysts, and seeks the development of new measurement techniques to determine the detailed composition and surface chemistry of nanoparticles.The central aims of this project are to develop techniques to enable the control of the size and determine the composition of nanoparticles and to advance our understanding of the mechanisms in electrocatalytic water splitting. This should ultimately contribute to the design of nanoparticle-based devices such as photochemical energy conversion systems and sensors. Students and postdoctoral researchers will be trained in cutting edge electrochemical techniques with relevance to alternative energy research.

教授罗伊斯W.位于查佩尔山的北卡罗来纳州大学的Murray得到了化学系化学催化项目的支持，以研究溶液分散的氧化铱纳米颗粒对水的电催化氧化，并提高测定非常小的纳米颗粒的组成和性质的分析能力。具体而言，该研究计划旨在更好地理解无载体和载体氧化铱纳米颗粒作为水氧化催化剂的有效机制，并寻求开发新的测量技术，以确定纳米颗粒的详细成分和表面化学。该项目的中心目标是开发能够控制纳米颗粒尺寸和确定纳米颗粒成分的技术，推进我们对电催化水分解机制的理解。 这最终将有助于设计基于纳米粒子的设备，如光化学能量转换系统和传感器。 学生和博士后研究人员将接受与替代能源研究相关的尖端电化学技术培训。
