Abstract

Abstract:

Splitting water into hydrogen and oxygen by dye-sensitized photoelectrochemical cell (DSPEC) is a promising approach to solar fuels production. In this study, a series of pyridine derivatives as surface additives were modified on a molecular chromophore and water oxidation catalyst co-loaded TiO₂ photoanode, TiO₂|RuP, 1 (RuP = Ru(4,4′-(PO₃H₂)₂-2,2′-bipyridine)(2,2′-bipyridine)₂, 1 = Ru(bda)(L)₂, (bda = 2,2′-bipyridine-6,6′-dicarboxylate, L = 10-(pyridin-4-yloxy)decyl)phosphonic acid). The addition of pyridine additives was found to result in up to 42% increase in photocurrent. Under simulated sun-light irradiation, TiO₂|RuP, 1, P₁ (P₁ = 4-Hydroxypyridine) produced a photocurrent density of 1 mA/cm ² at a bias of 0.4 V vs. NHE in acetate buffer. Moreover, the observed photocurrents are correlated with the electron-donating ability of the substituent groups on pyridine ring. Transient absorption measurements and electrochemical impedance spectroscopy revealed that surface-bound pyridine can effectively retard the back-electron transfer from the TiO₂ conduction band to the oxidized dye, which is a major process responsible for energy loss in DSPECs.
