Abstract

In this paper we described using ruthenium (Ru) nanoparticles for surface modification on our hybrid PV/a-SiC photocathode for hydrogen production by water splitting under sunlight. Ru nanoparticles with size less than 5nm in diameter made the photocathode showed promising results: in an aqueous electrolyte an anodic shift of photocurrent onset potential around 450 mV and an increase in the photocurrent density up to 1.8mA/cm2 from a negligible value. Initial discussion the influence of Ru nanoparticles is presented.
