Nanomaterials have wide range of applications such as catalysis,medicine, electronics, lubricants, medical implants, water purification, fuel additives, energy production etc. Studies on nanomaterials, such as transition metal oxides, cobaltite, ferrites, metals and their alloys have been undertaken. Chapter 1 includes general information about nanomaterials, their properties, classification (1D, 2D and 3D) on the basis of dimensions, significance of materials on nano scale and their applications. Several methods of synthesis of nanomaterials such sol-gel, co-percipitation, template...
