Facile construction of a Bi6O6(OH)3(NO3)3·1.5H2O/Bi2O2CO3 heterojunction with enhanced photocatalytic degradation activity
A Bi6O6(OH)3(NO3)3·1.5H2O (BBN)/Bi2O2CO3 (BOC) heterojunction was designed for the first time via a facile hydrothermal method. The photocatalytic performance of catalysts was evaluated by degrading Rhodamine B (RhB) under simulated solar light irradiation. It was found that the degradation rate of RhB by 25 wt%BBN/BOC was dramatically increased about 1.5 and 4.7 times compared with that of pure BOC and BBN, respectively. The enhanced photocatalytic performance migth be attributed to the effective separation of photoinduced electron-hole pairs, benefiting from the construction of heterojunction. Furthermore, the mechanism upon BBN/BOC composites photocatalyst was investigated, expecting this work will bring new insight into the theoretical study and application of semiconductors materials.
