The microporous nanocrystalline TiO₂ electrode with large surface roughness factor has been prepared on a conducting glass support.Modification of the TiO₂ electrode by in situ preparing quantum sized RuS₂ particles on the surface of TiO₂ electrode extends the optical absorption spectrum and photocurrent action spectrum into visible region.In addition,compared with RuS₂ bulk materials,a blue shift in both absorption spectrum and photocurrent action spectrum of RuS₂/TiO₂ electrode is observed and explained in terms of quantum sized effect.
