An Innovative Prototype for Photoelectrochemical Water Splitting

The goal of this research activity is to realize a photoelectrochemical device for green hydrogen production with a large active area (at least 10 cm2) and adequate production efficiency (at least 5%). Additionally, in parallel, innovative electrode materials will be developed via electrodeposition to enhance the photocurrent performance of the base photoelectrochemical cell (1cm2) previously developed with no critical raw materials. In particular, the photoanode is constituted by Fe2 O3 as semiconductor, Ti and P as dopants and the photocathode is constituted by CuO as semiconductor and nickel-based co-catalyst. An anionic polymer membrane works as electrolyte and as a gas separator.
