Synthesis of Nanomaterials—II (Chemical Methods)

Abstract

In this chapter we shall discuss some of the wet chemical methods to synthesize nanomaterials. There are numerous advantages of using chemical methods which are summarized in Box 4.1. In some cases nanomaterials are obtained as colloidal particles in solutions, which can be filtered and dried to obtain powder. We can obtain thin films or nanoporous materials by electrodeposition and etching. Advantages of chemical synthesis are manifold. In many cases very well known chemical reaction route can be optimized to obtain nanoparticles. Particles of different shapes and sizes are possible depending upon the chemicals used and reaction conditions.
