Nanotechnology is the future of our world. There will be a paradigm shift in the materials and application. New theories are emerging how such class of materials are functioning. In this book the simplest technique to produce advanced nanomaterial, titanium dioxide, is presented. The as synthesized nanomaterial was characterized using different techniques such as XRD, UV-Vis spectrophotometer, Transmission electron microscope (TEM), Scanning electron microscope (SEM), Energy dispersive spectroscopy (EDS).
