Abstract
Carbon-free fuel or green hydrogen production by photoelectrochemical water splitting is a promising way to replace the usage of fossil fuels on a large scale. In this project, photoanodes based on nanocomposites of monoclinic BiVO 4 by incorporating the nanoparticles of plasmonic metals (Au & Ag), reduced graphene Oxide (RGO), and carbon nanotubes (CNT) were fabricated for photoelectrochemical water splitting. The incorporation of reduced graphene oxide and carbon nanotubes revealed an increasing trend in current density through fast transportation of electrons. RGO/CNT/Ag/Au/BiVO 4 photoanode exhibited high system kinetics with the lowest over-potential of 200 mV.
