Investigation of CuO/ITO Photoelectrode Fabricated by PVD for Efficient Photoelectrochemical Water Splitting and Hydrogen Evolution.

Hydrogen and renewable fuels were generated using cost-effective and efficient electrocatalysts for water splitting. In this work, a CuO-based photocathode is used for the water splitting to generate hydrogen energy by PVD technique. The XRD analysis reveals the deposition of CuO thin film on ITO substrates, which is monoclinic.
