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

这笔启动资金授予北卡罗来纳州立大学，支持丹尼尔·l·费尔德海姆教授的研究。研究重点是在分离和排列的金属颗粒上进行光催化。多孔聚合物和氧化物膜，孔径范围从1纳米到300纳米，被用作光催化活性金属颗粒合成的模板。金属颗粒被用于系统地研究颗粒组成、大小、纵横比和与入射辐射有关的排列对非均相光催化反应的影响。该研究将促进对控制小金属颗粒表面光反应动力学和机理的几何因素的基本理解。这项研究可能会为工业上重要的有机化合物的合成带来更环保的途径。

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.
