Nanomaterials have a number of distinct features such as smaller size, high surface area, more reactivity, easy dispersability, and rapid diffusion that make them ideally suitable for environmental remediation besides other applications. It has been discussed in this monograph that properties of materials can be tailored to explore the possibilities of their applications to address challenging environmental problems faced today. Studies on the preparation of metal nanoparticles using both physical and chemical methods have been presented. Understanding and controlling the process ...
