A series of porous, single phase Sr0.96Y0.04Ti1-xNbxO3 samples was obtained using a wet synthesis method (modified citrate sol-gel) method. Temperature-programmed reduction (TPR) and temperature-programmed oxidation (TPO) measurements have shown high stability of the obtained material in variable (oxidizing/reducing) atmospheres. All samples exhibit high conductivity in hydrogen atmosphere with the highest value (around 1S/cm) in case of the material with nominal composition Sr0.96Y0.04Ti0.98Nb0.02O3. Moreover, measurements of the electrical resistance carried out for Sr0.96Y0.04Ti1-xNbxO3 samples in oxidation-reduction cycles confirmed the high stability of these materials and extremely rapid electrical response with change of the atmosphere . The results of the studies show that highly porous niobium and yttrium-doped strontium titanate materials can be used as a component for SOFC anodes or resistance gas sensor.
