description | Solution combustion synthesis (SCS) is an efficient approach to deliver materials with desirable properties directly in the nanoscale. Nevertheless, it is a very sensitive method and there are many parameters that influence the final materials’ properties and microstructure. In this work, four parameters that severely affect the combustion mechanism of formation for the final products, and as a result their final properties, are studied. These are the concentration of nitrates, the concentration of fuel in direct and slow heating and the time in furnace after the SCS is completed. It has been concluded that all these parameters affect the SCS process in a complicated way and an attempt has been made to explain the underlying mechanisms and processes that shape the final nanostructures. Finally, some of the as-synthesized Ni/NiO nanopowders were employed as catalysts and their activity was tested in the liquid-phase hydrogenation of maleic acid. |
