| 英文摘要 | A simple and effective method to prepare photocatalytically active electrodes for water oxidation is described in this paper. The precious-metal-free catalyst, Co4O4(O2CMe) 4(4-vinylpy) 4 (py = pyridine) was electrochemically polymerised on a RuP-sensitised TiO2 (RuP = [Ru(bpy) 2(4,4'-(PO3H2)(2)bpy(2))]Cl-2) and on a TiO2 surface codecorated with vinyl phosphate (Vpa) and RuP for applications in molecular photoelectrochemical (PEC) devices. With a Vpa chain as the anchoring group, the photoanode poly-Co4O4+Vpa/RuP/TiO2 demonstrated a significantly higher PEC performance compared to poly-Co4O4/RuP/TiO2. The introduction of a Vpa chain allows better immobilisation of catalyst and enhances the electron transport between the photosensitiser and the catalyst. A photocurrent density of similar to 100 mA cm(-2) was achieved in a Na2SO4 solution at pH 7.0 under a 0.4 V external bias, with a faradaic efficiency of 76% for oxygen production. |
