 Grafitic carbon nitride, GC3N4, is a promising material for use in solar fuel production. However, its performance is limited by the rapid recombination of electrons and low reaction dynamics. Boron-B was introduced into the large cavities between Tri-S-Triazin units and GC3N4 through coordination with two coordinate nitrogen, N, atoms. This modification improved the electronic citation from N, 2Px, 2Py, to B, 2Px, 2Py, with the same orbital direction in B doped GC3N4, which increased the charge transfer and localization, and thus the reaction dynamics. Additionally, B atoms doping changed the adsorption of carbon monoxide, CO, intermediate, and acted as active sites for methane, CH4, production. As a result, the optimal sample of 1% B-slash GC3N4 exhibited better selectivity for methane with approximately 32 times higher yield than that of pure GC3N4.
