Abstract
The photoelectrochemical (PEC) activity of metal oxide photoelectrodes for water-splitting
applications can be boosted in several different ways. In this study, we showed that PEC activity can
be significantly improved with a double-layer (crystalline-amorphous) configuration of WO3 thin
films irradiated with intense pulsed ion beams (IPIB) of a nanosecond duration. It was found that
IPIB irradiation promotes the formation of crystalline and sponge-like WO3 structures on the surface.
Due to an increase in the active surface and light scattering in irradiated samples, photocurrent
generation increased by ~80% at 1.23 reversible hydrogen electrodes (RHE).
