Hydrophilic bi-functional B-doped g-C3N4 hierarchical architecture for excellent photocatalytic H2O2 production and photoelectrochemical water splitting
文献摘要：
Graphitic carbon nitride(g-C3N4)has attracted great interest in photocatalysis and photoelectrocatalysis.However,their poor hydrophilicity poses a great challenge for their applications in aqueous environment.Here,we demonstrate synthesis of a hydrophilic bi-functional hierarchical architecture by the assembly of B-doped g-C3N4 nanoplatelets.Such hierarchical B-doped g-C3N4 material enables full utilization of their highly enhanced visible light absorption and photogenerated carrier separation in aqueous medium,leading to an excellent photocatalytic H2O2 production rate of 4240.3 μM g-1 h-1,2.84,2.64 and 2.13 times higher than that of the bulk g-C3N4,g-C3N4 nanoplatelets and bulk B doped g-C3N4,respectively.Photoanodes based on these hierarchical architectures can generate an unprecedented photocurrent den-sity of 1.72 mA cm-2 at 1.23 V under AM 1.5 G illumination for photoelectrochemical water splitting.This work makes a fundamental improvement towards large-scale exploitation of highly active,hydrophilic and stable metal-free g-C3N4 photocatalysts for various practical applications.
