Description A biphasic copper oxide thin film of grass-like appendage morphology is synthesized
by two-step electro-deposition method and later investigated for
photoelectrochemical (PEC) water splitting for hydrogen production. Further,
the thin film was characterized by UV–Visible spectroscopy, x-ray diffraction
(XRD), Scanning electron microscopy (SEM) and PEC techniques. The XRD
analysis confirms formation of biphasic copper oxide phases, and SEM reveals
high surface area grass appendage-like morphology. These grass appendage
structures exhibit a high cathodic photocurrent of � 1.44 mAcm�2 at an applied
bias of � 0.7 (versus Ag/AgCl) resulting in incident to photon current
efficiency (IPCE) of � 10% at 400 nm. The improved light harvesting and
charge transport properties of grass appendage structured biphasic copper
oxides makes it a potential candidate for PEC water splitting for hydrogen
production.
