1. Desenvolvimento de catalisadores de óxido de ferro ou óxido de zirconio sulfatado para a redução de óxidos de nitrogênio com propano.
Nitrogen oxides are responsible for the three of the main phenomena related global pollution. The photochemical smog, the acid rain and the pollution of continental water by nitrate species, as well as the greenhouse effect, are related to nitrogen compounds. In the last decades several technologies have been proposed and used to reduce the emissions of nitr

2. Efeito das condições de preparação sobre as propriedades do óxido de zircônio sulfatado contendo ferro.
Sulfated oxide-based catalysts have found several industrial applications mainly in reactions which demand for strong acid sites. In order to develop methods to get acidic oxides, the effect of the preparation methods on the properties of iron-doped zirconia oxides was studied in this work.The precursors were prepared by process sol-gel from iron nitrate and
