Photocatalysis at Isolated and Aligned Metal Particles: Effect of Particle Size and Shape on Heterogeneous Photochemical Reactions

这项授予北卡罗来纳州立大学的初学者奖金支持丹尼尔·L·费尔德海姆教授的研究。研究的重点是孤立和排列的金属颗粒的光催化作用。多孔聚合物和氧化物膜的孔径从1 nm到300 nm不等，被用作合成光催化活性金属颗粒的模板。金属颗粒用于系统地研究颗粒组成、尺寸、长径比和相对于入射辐射的取向对多相光催化反应的影响。这项研究将促进对控制金属小颗粒表面光反应动力学和机理的几何因素的基本理解。这项研究可能会导致合成具有重要工业意义的有机化合物的更环保的方法。

This starter grant award to North Carolina State University supports the research of Professor Daniel L. Feldheim. The research focusses on photocatalysis at isolated and aligned metal particles. Porous polymer and oxide membranes, with pores ranging in diameter from 1 nm to 300 nm, are used as templates for the synthesis of photocatalytically-active metal particles. The metal particles are used for the systematic investigation of the effects of particle composition, size, aspect ratio, and alignment with respect to incident radiation on heterogeneous photocatalytic reactions. The research will advance the fundamental understanding of the geometric factors that govern the kinetics and mechanisms of photoreactions at small metal particle surfaces. The research may lead to more environmentally-friendly routes to the synthesis of industrially important organic compounds.
