Photoanode immobilized molecular cobalt based oxygen evolving complexes with enhanced solar to fuel efficiency
We describe a trinuclear phenanthroline, linked with a Schiff base cobalt complex, displaying superior performances in homogeneous electrocatalytic water oxidation reaction in neutral solution with an extraordinary turnover frequency of 119 s 1. Subsequently, the complexes are successfully immobilized on the surface of TiO2 nanorod arrays for improvement of photoconversion efficiency of three times that of pristine photoanode under simulated solar irradiation.
