Stratified Materials Synthesized in the Liquid Phase

Abstract

Stratified materials are defined as materials with artificially controlled and designed stratifications. They are illustrated by thin nano or stacked layers formed on the surface of semiconductors. The present research is aimed at enhancing the existing properties and also developing novel properties in fine particles through the formation of controlled and designed stratified layers on their surfaces (not limited to single crystals), which is otherwise difficult to accomplish through conventional particle engineering. Furthermore, in this study, methods for control and design of advanced stratified layers at the atomic level on the surface of ultrafine particles are also to be developed and characteristic properties realized through stratification are to be explained by analyzing their structure at nanometer levels. Therefore, the novel word stratified materials is used to identify controlled synthesis of well-defined stratification at atomic levels on solid surfaces. Likewise, the goal of the development of stratified materials is to supply novel materials with highly advanced stratified structure, to yield effective electromagnetic, optic, bioactive, adsorptive or catalytic properties. In this text, we shall introduce a photocatalyst with stratified structure as an example.
