Facile synthesis of new Z-scheme Bi2WO6/Bi2MoO6 p–n junction photocatalysts with high photocatalytic activity: Structure, kinetics and mechanism approach
Source abstract
Abstract
Abstract 3D flower like metal oxide nanocomposites, Bi2WO6/Bi2MoO6, were designed and synthesized. The physical, electrochemical and optical properties as well as phase structure and morphology of photocatalysts were analyzed by XPS, XRD, SEM, IR, TEM, BET, PL, PC, EDX and DRS. Bi2MoO6 elevated the Bi2WO6 photocatalytic activity and investigation of optical band gap showed that Bi2WO6/Bi2MoO6 is a visible light activated photocatalyst. The fabricated Bi2WO6/Bi2MoO6 exhibited high photocatalytic performance and excellent reusability capability under visible light irradiation. Acid blue 92 was used as an azo dye for investigation of photocatalytic activity and it was observed that after 20 min of visible light irradiation, the dye was degraded completely. Different parameters such as dye concentration, weight percent ratio of Bi2MoO6 to Bi2WO6, pH and catalyst dosage were optimized. Strong oxidative ability, efficient charge separation and transfer the electron-hole through the Bi2WO6/Bi2MoO6 nanostructure are main reasons for high photocatalytic activity. The photocatalytic reaction kinetics and mechanism with the Bi2WO6/Bi2MoO6 were studied. The photoreaction mechanism mode was also proposed.
