| Outline of Final Research Achievements |
Non-noble metal thin film catalysts for oxygen reduction reaction (ORR) have been prepared by magnetron sputtering method using Ti2O3 plate as a target. Thus prepared thin film catalysts consisting of Ti2O3 phase having high electrical conductivity shows ORR activity and their performances can be improved by optimizing the substrate temperature, sputtering gas pressure and substrate-target distance during the film deposition. Optimized Ti2O3 thin film catalysts show higher activity for ORR than previously reported TiO2-x catalysts. Furthermore, it was found that MFe2O4・rGO (reduced graphene oxides) hybrid catalysts as well as porous carbon catalysts containing Co nanoparticles prepared by pyrolysis of zeolitic imidazolate frameworks (ZIFs) act as efficient non-noble metal catalysts for oxygen reduction reaction.
