Abstract

Abstract: Recently the increasing research interest has been devoted towards the development of semiconductor-metal nanocomposites consisting of different classes of materials with coherent interfaces. This type of nanostructures combines materials with distinctly different physical and chemical properties to yield a unique hybrid nanosystem with multifunctional capabilities, and tunable or enhanced properties that may not be attainable otherwise. The accumulation of the nanocomposites creates great opportunities also a tremendous challenge to apply these materials for highly efficient energy conversion. In addition to promote the charge separation, the welcome feature for a semiconductor-metal nanocomposite also includes the electronic coupling between the semiconductor and metal domains. The primary objectives of this research area are: ①to develop facile process to produce high quality semiconductor nanocrystals; ②to build the feasible approaches for the deposition of metals on semiconductor nanocrystals; ③to understand the underlying chemistry in the size and structure control and the mechanisms for the next stage of development in both synthesis and rational manipulation of nanocomposites; ④to explore various applications of the nanocomposites in energy conversion area.

Key words: semiconductor, noble metal, nanocomposites, electronic coupling, energy conversion
