Description
Summary:[Display omitted] •A novel ternary photocatalyst with sandwich structure was synthesized by MnFe2O4@carbon microspheres and g-C3N4.•The Mn@PC/g-C3N4 presented excellent photodegradation efficiency for MO (99.3%).•The carbon microspheres acted as an electron avenue between MnFe2O4 and g-C3N4. In this study, ternary photocatalysts (Mn@PC/g-C3N4) were prepared by carbon microspheres, MnFe2O4, and g-C3N4. The structure, morphology, and optical properties of the as-obtained photocatalysts were characterized systematically. Photodegradation of methyl orange (MO) and lemon yellow (LY) under visible light irradiation were carried out to evaluate the photocatalytic performance of Mn@PC/g-C3N4. The impact of ratio of Mn@PC and Mn@PC/g-C3N4 on the photocatalytic activities were investigated. The 20% Mn@PC/g-C3N4 presents the optimum photodegradation rate, which is 6.2 times higher than that of bulk g-C3N4. The superior photocatalytic performance can be ascribed to the enhanced light responsing capacity and light harvesting ability of Mn@PC/g-C3N4 and effective separation of photo-induced charges.
