Morphology Changes of Nanocrystals Induced by a Small Amount of Water in the Composite-Hydroxide-Mediated Approach

Abstract

The influence of water on morphology and structure of nanomaterials synthesized by the composite-hydroxide-mediated (CHM) approach has been systematically investigated. A small amount of water would affect the morphology and size, while a large amount of water would affect not only the morphology, but the structure of nanomaterials. The experimental results indicate that the nanocrystals prefer anisotropic growth and form more regular shape by the CHM route to hydrothermal synthesis.
