Abstract

In this work, a plasma treatment is employed to modify the surface properties of g-C₃N₄ photocatalyst to enhance its photocatalytic performance. A suite of characterization methods are used to investigate the influence of plasma treatment on the surface properties, such as morphology, hydrophilicity and chemical bonding states. The comparative photocatalytic performance of pristine g-C₃N₄ and the plasma-treated g-C₃N₄ (PT-g-C₃N₄) for the degradation of Rhodamine B (RhB) are demonstrated. The degradation efficiency under visible light irradiation for PT-g-C₃N₄ is >2.0 times as high as that of pristine g-C₃N₄. The remarkably enhanced photocatalytic performance for pollution degradation results from the optimization of the surface properties induced by plasma treatment. These findings may provide a promising and facile approach to design high-performance photocatalysts.
