Abstract

Q-sized silver sulfide particles have been embedded into porous titanium dioxide electrodes. The influence of particle size and pH value of the electrolyte on the photocurrent spectra and on the shape of the cyclic voltammograms have been investigated. The specific ionic adsorption and its effect on thermodynamic potentials are discussed.
