| Popis: | The novel peanut-like shaped MoSe2/BiVO4 composites were fabricated via a facile two-step hydrothermal method and their photocatalytic activity was evaluated by the degradation of glyphosate under the visible light irradiation. The efficient transfer of photogenerated carriers and the charge separation were confirmed by photoluminescence spectra (PL), electrochemical impedance spectroscopy (EIS) and photocurrent. The coupling of MoSe2 and BiVO4 remarkably enhanced the photocatalytic activity. The 0.15MoSe2/BiVO4 composite showed the highest photocatalytic performance for the degradation of glyphosate among all the as-prepared photocatalysts and presented the high stability and good reusability in the photocatalytic reactions. |
