Abstract Scope |
A Ni-MgO composite material has been prepared through an alternative route based on sulfates thermal decomposition in the presence of a reducing agent (e.g. sulfur, carbon) or a catalyst (e.g. Pd, Ni). The present work has its purpose associate with the development of a unitary process in which sulfates can be used to synthesize composite materials. Therefore, synthetic nickel and magnesium sulfates were used to prepare a mixture that was submitted to a thermal decomposition in reducing conditions as well as in the presence of catalysts. The study covers a thermodynamics assessment, thermogravimetric analysis in addition to reaction products materials characterization by means of SEM/EDS, XRD and FTIR. It was identified that both additives enable the chemical transformations in lower temperatures, with reductive decomposition as the most effective method. The reaction products were verified as essentially nickel and magnesium oxide. |
