Abstract

A photochemical system utilising a modular approach characterised through interpretation of photoelectrochemical measurements is discussed. A photoanode was prepared by the chemisorption of a photosensitiser, cis-bis-(2,2'-bipyridine)-(4,4'-bis-(methyl)phosphonato-2,2'-bipyridine)ruthenium(II) dichloride (RuL2L'2+), to a mixed nanoporous nanocrystalline RuO2:TiO2 thin film, calcined on a fluorine doped SnO2 conducting glass substrate. Similarly, an electron relay molecule, 1-ethyl-1'-(2-phosphonoethyl)-4,4'-bipyridinium dichloride (EVP), was covalently bound to a platinum electroplated nanoporous nanocrystalline TiO2 thin film, and the electrodes connected in a photoelectrocatalytic cell (PCC). Irradiation with lamda > 420 nm gave a measurable photocurrent. Interpretation of the photocurrents obtained from this assembly provides a means for understanding photochemical reactions under low light intensities. Optimised conditions of the electrolyte solution were determined to be pH = 5 and illumination yielded eta = 0.0036% with an apparent quantum yield (AQY)= 1.6%.
