Comparison of Hydrogen Sensing Characteristics of CrNbO₄Prepared by Solid-State Route and Solution Combustion Synthesis (SCS)

Abstract:

Solution combustion synthesis is adopted for the preparation of CrNbO₄. Its electrical conductivity is found to be less than that of the solid state synthesized compound. Hydrogen sensing property of solution-synthesized compound is comparable to that of solid-state prepared compound up to about 400 vppm of H₂. However, the sensor signal saturates beyond 2500 vppm of H₂. Hydrogen sensing property is compared between the combustion derived and solid state prepared compounds.
