Nanopowders of TiO2 obtained by combustion reaction: effect of fuels

Almeida E.P., Coutinho J.P., Freitas N.L., Kiminami R.H.G.A., Costa A.C.F.M., Lira H.L., Universidade Federal de Campina Grande, BR

The synthesis by combustion reaction to obtain TiO2 has been studied by several researchers and using different fuels. Thus, this study aimed to evaluate the effect of fuel (citric acid monohydrate, aniline, oxalic dihidrazida and [...]

Preparation of ZnAl2O4 Catalytic Support by Combustion Reaction: Influence of Type of Heating Source

Leal E., Viana K.M.S., Kiminami R.H.G.A., Meneghetti S.M.P., Costa A.C.F.M., Lira H.L., Universidade Federal de Campina Grande, BR

The aim of this work is to evaluate the esterification activity of ZnAl2O4 catalysts obtained by different ways of heating (IU-plate, IIU-muffle furnace and IIIU-microwave oven) during the combustion synthesis using urea as reducing agent, [...]
