Surfactant could change the physical and chemical property of metal oxide. Chemically synthesis metal oxide have special property such as size orientation and specific active area. In this way semiconducting metal oxide such as PbO2 in presence of surfactant plays an important role due to controlling factors such as CMC value of missile, hydrophobicity and hydrophilicity of surfactant, which leads to formation of nano particles in defined morphology. On these basis, we have synthesized nano structured PbO2 from the mixture of PVP and Triton x 100 at room temperature. The optimized concentration of both surfactants was studied. The material is characterized by the XRD, SEM and TEM. As a result PbO2 to rod like morphology was achieved with nano in size . |
