• BCN nanosheets
• Thermal substitution
• Photoelectrochemical performance

A series of flake-like BCN compounds were produced by calcination at different reaction temperatures via thermal substitution of C atoms with B atoms of boric acid substructures in graphitic carbon nitrides (g-C3N4). The structural and optical properties of the samples were characterized by XRD, TEM, HRTEM, XPS and UV-vis absorption. The photoelectrochemical (PEC) performance of all samples were characterized through photocurrent and electrochemical impedance spectroscopy (EIS) measurement. The test results demonstrated that BCN nanosheets exhibited higher PEC performance with increasing substituted amount of boron.
