Green synthesis and characterization of SnO2 and ZnO nanoparticles: Study their electrical conductivity and gas sensing properties

In the recent years nanomaterial’s directed attention of many researchers because their vast application in the field of research. Nanomaterials that can used as catalyst have potent application in the field of electrical conductivity, Gassensing, optical materials, ceramic materials, signal transductors, optoelectronic devices. The present study involves preparation of transition metal oxides such as SnO2 and ZnO(Green method).In addition to these materials thousands of materials have been prepared successively and reported their application in same fields.SnO2 and ZnO, prepared by Co-precipitation method, characterization was accomplished by XRD for Nanomaterial size confirmation. Their thick films prepared by screen printing method ,electrical conductivity was measured by a conventional apparatus. Gas sensing properties of Ammonia gas performed by preparing thick films of SnO2& ZnO nanomaterials. Good results were recorded for conductivity properties and gas sensing properties of prepared nanomaterial of SnO2 and ZnO.
