Preparation of NiFe2O4 and ZnFe2O4 Samples by Combustion Reaction and Evaluation of Performance in Reaction Water Gas Shift Reaction - WGSR

This paper aims to synthesize and characterize nanosized nickel and zinc ferrites (NiFe2O4 and ZnFe2O4) samples by a combustion reaction method, using glycine as fuel. The performance in HT-WGRS reaction the samples was investigated. The results showed that the combustion reaction was effective in the production of major phases of the spinel ferrite (crystallite sizes of 44 and 27 nm) and presence of the secondary phases, such as Ni and ZnO, with surface area 3 and 115 m2/g for NiFe2O4 and ZnFe2O4, respectively. HT-WGSR activity was achieved (80%) to NiFe2O4 ferrite in the temperature range of 300 - 500°C.
