Abstract

Ultrathin graphitic carbon nitride (g-C₃N₄) nanosheets were synthesized via thermal exfoliation of bulk urea-derived g-C₃N₄ under an argon atmosphere. As a visible-light responsive photocatalyst, this material exhibits a much superior photocatalytic activity in pollution degradation and H₂ evolution than bulk g-C₃N₄, as a result of the extended region of visible light response and the enhanced surface area of ultrathin g-C₃N₄ nanosheets. These findings may provide a promising and facile approach to the design of high-performance photocatalysts.
