Abstract
We employed a Pd-loaded TiO2 film as a simple model for the metal-deposited photocatalyst and carried out spatial mapping of reaction products formed by the photocatalytic reactions in a Fe(CN)63−⁄4− aqueous solution using a microelectrode. The experimental data were simulated with a diffusion model solved by the finite difference method. The results indicate that the spatial resolution of ca. 70 μm can be obtained with a distance of 30 μm between the sample surface and the microelectrode.Keywords
