摘要
Theoretical calculations predicted that the hybrid o i two-dimensional/two-dimensional (2D/2D) Mo-g-C3N4 (Mo-CN) and Bi2O2CO3 (BOC) materials led to stronger interfacial interaction due to the introduction of Mo atom in contrast with bare graphitic carbon nitride (g-C3N4; CN) and BOC. Furthermore, introduction of Mo showed the prominent role in the charge distribution between the interfaces of Mo-CN and BOC. In combination with the theoretical simulation, we designed and synthesized 2D/2D hybrid materials of CN/BOC and Mo-CN/BOC. We discovered the strong interfacial interaction between Mo-CN and BOC could induce oxygen vacancies on BOC, whereas CN, BOC showed no obvious oxygen vacancies even with interfacial interaction. Evidently, Mo-CN/BOC can improve the migration of carrier and the inhibition of electron-hole pair recombination, therefore enhancing the photocatalytic NO oxidation activity. This work reveals that a 2D/2D hybrid of Mo-CN/BOC material with strong interfacial interaction can be formed to achieve more excellent photocatalytic activity than the traditional 2D/2D hybrid of CN/BOC, providing a new insight into the efficient construction of photocatalysts.
