Hydrazinated derivatives are very good precursor for synthesizing nanostructures. These precursors have been prepared and characterized by infrared spectra and thermal analysis. The hydrazine content and metal compositions of the synthesized precursors were determined by standard procedures of chemical analysis [7]. Nowadays, spectroscopic techniques such as AAS (Atomic Absorption Spectroscopy) and EDXA (Energy Dispersive X-ray analysis) are also very useful for determining the metal contents in the precursors and in their oxides. Hydrazine is one of in the series of compounds called hydronitrogens. The chemistry of hydrazine is appealing since it has a potent N-N bond, two electron pairs and four substitutable hydrogen atoms. Having two active nucleophilic nitrogens and four substitutable hydrogens, hydrazine is the starting material for many heterocyclics, where the ring contains one to four nitrogen atoms as well as other heteroatoms [8-12]. Hydrazine is the simplest diamine, with two lone pairs over nitrogen atom is capable of forming variety of complexes with metal salts [13-20]. The coordination of hydrazine to the metal ion in several complexes can either be unidendate, bidendate or bridged ligand [21-32]. Nowadays, hydrazine derivatives have been well utilized for synthesizing nanostructures. This review mainly focuses the current status of studies on synthesis of nanomaterials from various methods in presence of hydrazine followed by a structural confirmation of nanoparticles through XRD, SEM, TEM and their applications in magnetic [10], electric [11], ferrofluid [12], semiconductors [13] etc, and also concentrating on the publications, which have appeared from the last ten years. Literature Review Preparation of Nanomaterials from Hydrazine derivatives There are many methods available for the preparation of nanosized metal oxides and mixed metal oxides from Abstract Nowadays, the properties and potential applications of nanomaterials find wide spectrum in optical, electronic, catalytic, magnetic, biomedicals and so on. The role of metal hydrazine derivatives provides a new entrance for synthesizing nanomaterials. Among several methods, metal hydrazine derivatives from combustion method receives much attention due to its effective simple methodology and low cost. An approach is made to herein this review, specifically discussed about the synthesis of nanomaterials with different particle size and morphology prepared from metal hydrazinated precursors which mainly depends on molecular weight of the ligand, reaction time, temperature, power of sonication, reducing and capping agents etc., followed by structural confirmation of nanoparticles and their applications in various fields. Keywords:Nanomaterials, hydrazine derivatives, morphology, particle size. *Correspondence Author: R Manimekalai Email: rmanimekalai13@gmail.com
