Abstract
- Abstract: In this work, a method for preparing nanomaterials shaped into powder and balls (diameter: 1–2mm) is developed. The synthesis is performed by an oil-drop process using a sol–gel method. During the preparation, the sol was improved by the inclusion of some additives such as methylethylketone (MEK), Butvar (But) and ethylmethacrylate (EMC). BaTiO3 and Ba0.67Sr0.33TiO3 perovskite-type compounds synthesized by both procedures present the same physical–chemical properties. The development of this sol–gel process enables the formation of these shapes in amounts as large as the 50g scale in a laboratory. The use of synthesized spherical pellets in a non-thermal plasma reactor enables the increased conversion of ethanol when acting as a pollutant. [Copyright &y& Elsevier]
