AbstractCHE-0615606Kurtz/LSUProfessors Richard Kurtz and Phillip Sprunger in the Physics Department at Louisiana State University are examining the photocatalytic reaction mechanisms of organic oxidation at metal decorated titanium dioxide nanoparticle surfaces. With the support of the Analytical and Surface Chemistry Program, this team is using scanning probe microscopy and synchrotron based photoemission methods to characterize metal decorated titania particles which have been capped with a layer of titania. The capping layer is thought to prevent oxidation and agglomeration of the nanometal antennae on the photocatalytic particles. Significant broader impacts will result in the application of these materials in environmental remediation and photocatalytic water splitting, if this conceptual advance can be successfully implemented. Metal decorated titania nanoparticles can be tuned to absorb solar radiation and used as photocatalysts for water splitting and organic oxidation reactions. Professor Kurtz and his coworkers at LSU are applying surface characterization methods to titania capped nanoparticles, in an attempt to understand photocatalytic mechanisms on these materials. Application to environmentally relevant systems may result.

Louisiana州立大学物理系理查德·库尔兹（Richard Kurtz）和菲利普·斯普伦格（Phillip Sprunger），摘要-0615606Kurtz/Lsuprofersess，正在研究金属装饰二氧化钛纳米粒子表面的有机氧化的光催化反应机制。 在分析和表面化学计划的支持下，该团队使用扫描探针显微镜和基于同步加速器的光发射方法来表征已经用一层钛覆盖的金属装饰的钛颗粒。 上限层被认为可以防止光催化颗粒上纳米触角的氧化和团聚。 如果能够成功实施这种概念上的进步，则会导致这些材料在环境修复和光催化水分裂中的应用。金属装饰的钛纳米颗粒可以调节以吸收太阳辐射，并用作水分裂和有机氧化反应的光催化剂。 Kurtz教授及其在LSU的同事正在将表面表征方法应用于二氧化钛限制的纳米颗粒，以尝试了解这些材料上的光催化机制。 可能会导致对环境相关的系统的应用。
