Enhanced boron modified graphitic carbon nitride for the selective photocatalytic production of benzaldehyde

Graphitic carbon nitride is a non-metal photocatalyst easily prepared from nitrogen organic compounds through green synthesis processes that do not require the use of solvents. This work proposes boron to modify layered g-C3N4 structure by incorporating B induce defects aimed at enhancement photocatalytic activity. Boron-modified graphitic has been obtained using elemental and NaBH4 as precursors. The XRD FTIR characterization results suggest C N positions can be replaced B, resulting in modified which tri-s-triazine units are altered. exchange atoms differed precursor according analysis chemical properties surface. Thus, had preference with atoms, whereas led substitution into positions. difference considerably affected activity during selective oxidation benzyl alcohol. sample highest rate selectivity linked lesser recombination effect than other samples photoluminescence tests. provides evidence about convenience selection precursors modification g-C3N4. photon absorbance was determined for estimation quantum yield. Although quite similar all cases, different registered kinetics maximum efficiency 0.15% NaBCN.
