Outline of Final Research Achievements

New Ru-Pd heterobimetallic complexes were synthesized and structurally characterized utilizing 6,6''-bis(phosphino)-2,2':6',2''-terpyridine as a scaffold for the metal-metal bond. The dicationic Ru-Pd complex was found to exhibit high catalytic activity as a photocatalyst for photochemical re-duction of CO2 to CO under visible light irradiation. This study established a new design of transition metal catalysts that tune photoredox catalysis with metalloligands.
