High performance visible-light driven photocatalysts of Bi2MoO6-g-C3N4 with controllable solvothermal fabrication

Heterostructure Bi2MoO6-g-C3N4 composites with different pH values were prepared by a facile impregnation method. The as-prepared samples were characterized by various physicochemical techniques, such as XRD, SEM, TEM, HRTEM, UV-vis and FT-IR. The obtained samples exhibited highly photocatalytic activity toward the degradation of rhodamine B (RhB) under visible light irradiation. The Bi2MoO6-g-C3N4 sample obtained at pH = 7 exhibited the best photocatalytic performance. Moreover, the prepared sample showed good stability and recyclability properties which were beneficial for its practical application.
