Schematic illustration of the proposed mechanism of BCNO in catalyzing the degradation of MB upon light irradiation. The positively charged MB was selectively absorbed on the N2B-OH sites. The band structures of BMH03 were determined via UPS and Tauc plot (Fig. 6 and Additional file 1: Fig. S17). The redox potentials of O2/O2 = − 0.13 eV vs ENHE and H2O/OH = 2.72 eV vs. ENHE are given in black dashed lines as reference
