ZnO/ CdO by Sol Gel Method and Verify it's Morphology as a Passive Defense Agent

Nano composite ZnO –CdO has been synthesized by sol –gel method. these compounds have been used as adsorbing decontamination agent for NBC warfare, neutralization of agricultural pesticide and so on.They can definitely be used as a modern passive defense agents. Zinc and cadmium oxides are prepared by Zinc and cadmium nitrate respectively.Mixture of ethanol- H2O has been used as solvent. The nitrates, solvent and gel maker were mixed together, then the solution converted to gel by heat. The gel has been pyrolyzed at 600-800ºC for eight hours. Their nitrates have been converted to nano composite by calcinations. Concentration of solvents, PVA, nitrates and temperature have affected the morphology of nano composite. Structure and morphology of nano composite were studied by SEM and XRD and the size of nano composite considered 4 nano meter.
