In this paper, we investigate the reaction mechanism followed during the solution combustion synthesis of transition metals (Cu, Ni and Co). Metal nitrates were mixed with a choice of fuel (glycine, and urea) and dissolved in deionized water to get a homogeneous solution with uniform properties. This solution is heated over a hot plate heater to initiate the highly exothermic combustion reaction resulting in the synthesis of metals/metal-oxides. Theoretical models describing combustion synthesis and thermodynamic calculations were used as guiding tools to predict the expected outcomes and to modify the experimental parameters leading to desired phase (metal/metal-oxide) synthesis. TGA-DTA analysis of the reactants (metal-nitrates and fuel) along with FTIR analysis of gases released during decomposition of reactants at various temperatures helped us in developing a consistent mechanism to describe the steps followed during combustion synthesis. These materials are currently being used as catalysts and their catalytic properties will also be discussed in the paper.
