Summary on Grant Application Form |

This proposal is concerned with the use of electrical measurements (both DC and AC) to characterise the electrical properties of mixed oxide catalysts. The aim of the work is to improve understanding of the catalyst by establishing the significance of different conduction modes (ionic or electronic) on catalytic activity, and to assist industry by developing electrical methods (both DC and AC) capable of rapidly predicting and/or monitoring catalytic activity for a range of catalyst systems.The system selected for study in this work is the oxidation of ethane to ethylene over a Mo-V-Nb oxide catalyst. It is proposed that the optimum catalyst will exhibit the highest possible oxygen-ion conductivity, combined with much higher electronic conductivity. If this is successfully demonstrated in this work, then catalyst development will be targeted at increasing oxygen-ion conductivity by eg supporting on established oxygen-ion conductors such as ceria, plus enhancing electronic conmductivity by selection of suitable metals eg Pd, Ru etc.
