In this work, a method for preparing nanomaterials shaped into powder and balls (diameter: 1–2 mm) 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 50 g 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.
