Abstract
- The incorporation of nonmetal group dopants into a graphitic carbon nitride (g-C <subscript>3</subscript> N <subscript>4</subscript> ) framework is fabricated by adding a small amount of hexamethylenetetramine during the thermal polymerization process. The material shows an excellent visible-light photocatalytic H <subscript>2</subscript> production performance that is eight times higher than bulk g-C <subscript>3</subscript> N <subscript>4</subscript> . This outstanding performance is ascribed to the introducing of N-doped carbon, which not only enhances the light absorption and favorsa narrower band gap, but also upshifts the conductionband (CB) potential, resulting in a better reduction ability of electrons. This discovery has potential significancefor the designing of high performance, economic, and environmental friendly photocatalyst for solar energy conversion.
