We developed photoelectrochemical water splitting using as photoanode a thin film of graphitic carbon nitride containing graphitic carbon domains, prepared by vapor deposition of melamine with glucose. The graphitic carbon domain, whose content is modulable over a wide range, enhances the visible light absorption, electrical conductivity, and electron-hole separation. And optimizing it for visible light (420 nm) water splitting. the observation was the residence of radicals in the gCN films containing gC domains even in the dark at ambient temperatures, which possibly facilitate the evolution of oxygen from the photoanode surface. These properties position the gCN-co-gC film as a high-performance PEC system, achieving high photocurrent.
