Towards efficient and robust anodes for water splitting: Immobilization of Ru catalysts on carbon electrode and hematite by in situ polymerization
2016 (English)In: Catalysis Today, ISSN 0920-5861, E-ISSN 1873-4308Article in journal (Refereed) Published
Ru-bda based molecular water oxidation catalysts 1 and 2 (H2 bda = 2,2′ –bipyridine–6,6′ –dicarboxylic acid) containing a thiophene group are attached to the surfaces of electrodes by the method of elec- tropolymerization. The Ru-bda molecular catalyst functionalized graphite carbon electrode can catalyze water oxidation efficiently under a overpotential of ca 500 mV to obtain current density of 5 mA cm−2 ; and the similarly functionalized photoelectrode based on -Fe2 O3 (hematite) film can work as an photoanode for light driven water splitting.
