During in situ thermal co-polymerization of melamine using boric acid and thiourea as the dopant, graphitic carbon nitride (g-C3N4) co-doped with boron and sulfur has been successfully synthesized. The crystallographic, morphological, and spectroscopic data of synthesized materials were characterized through powder X-ray diffraction, transmission electron microsopy, elemental mapping, energy dispersive X-ray spectroscopy, X-ray photoelectron spectroscopy, photoluminescence (PL), time-resolved PL (TRPL), and UV–vis diffuse reflectance spectroscopy techniques. The boron and sulfur doping in carbon nitride lattice enhance light absorption, charge separation, and migration and increase the effective surface area, constructing it to be the best photocatalyst among the bulk g-C3N4 as well as singly doped C3N4 counterparts for the generation of hydrogen. The introduction of dopants into the g-C3N4 framework could tune the electronic property, suppress the recombination of photogenerated charge carriers, and trap...
