Abstract

Graphitic carbon nitride (g-C3N4) is a promising metal-free polymeric photocatalyst with a visible light response, but current technologies fail to obtain high quality films for photoelectric devices. Herein, an efficient solvothermal strategy has been developed to prepare continuous and complete graphitic carbon nitride films. The resulting films exhibit a remarkable enhancement in photoelectrochemical performance, much superior to the thermal condensation g-C3N4 films. This is attributed to the red-shift of visible light absorption and the improvement of charge separation and transport. Importantly, the general, efficient and one-step wet-chemical strategy opens up new possibilities for carbon nitride in photoelectric devices based on renewable solar energy applications.
