Abstract
Graphitic carbon nitride (C3N4) hexagonal microprisms were synthesized via a self-assembly route using (NH4)2CO3 as a structure-directing reagent. It shows that the extraordinary hierarchical structure is favorable to improving the photocatalytic activity of C3N4 toward water splitting under visible light irradiation (λ>420nm). The photocatalytic H2-evolution rate on the microprisms is 185 µmol/h, 16.8 times higher than that over bulk C3N4. The enhanced photocatalytic performance of the as-prepared microprisms mainly originates from the characteristic micro-nanostructure, possessing enlarged surface area for efficient charge separation.
