Synopsis

Novel photocatalyst structure was successfully synthesized by a simple chemical method, it involves copper sulfide deposited on silicon nanowires by CBD. The Cu2S@Si-NW structure was used as a cathode material for the photoelectrochemical reduction of CO2. the morphology and optical properties of the developed cathodes were characterized by SEM and UV-visible spectroscopy. For photoelectrochemical characterizations we use a potentiostat station. We carried out linear voltammetry (LSV) in the dark and under white light irradiation and chronoamperometry is carried out to study the stability of our photocathodes.
