The ternary photocatalyst Mn@PC/g-C3N4 exhibited superior photocatalytic performance in the degradation of methyl orange and lemon yellow under visible light irradiation, with 20% Mn@PC/g-C3N4 showing the highest photodegradation rate.
In this study, ternary photocatalysts (Mn@PC/g-C3N4) were prepared by carbon microspheres, MnFe2O4, and gC3N4. 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/gC3N4 and effective separation of photo-induced charges.
