SYNTHESIS OF METAL NANOSTRUCTURES BY PHOTOREDUCTION

Bo Hu, Hong-Yan Shi and Shu-Hong Yu

Abstract

Metal nanostructures with the size range of 1-100 nm, featuring unique physical and chemical properties that arise from their quantum size effects and high surface areas, have been the focus of recent scientific research. Among a variety of synthetic methods, the photoreduction method represents a promising strategy for controlled synthesis of metal nanostructures with different sizes, shapes and composition. In this review, the latest development on synthesis of metal nanostructures by UV radiation, γ-ray radiation, and laser radiation methods will be overviewed with specific examples to illustrate how to generate metal nanostructures with unusual structural specialty and complexity. The perspectives on combination of this method with solution processing and interfacial reactions are given.
