The novel peanut-like shaped MoSe/BiVO 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 MoSe and BiVO remarkably enhanced the photocatalytic activity. The 0.15MoSe/BiVO 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.
新型花生状 MoSe/BiVO 复合材料通过简便的两步水热法制备，并通过可见光照射下草甘膦的降解来评估其光催化活性。光致发光光谱 (PL)、电化学阻抗谱 (EIS) 和光电流证实了光生载流子的有效转移和电荷分离。MoSe 和 BiVO 的耦合显著提高了光催化活性。在所有制备的光催化剂中，0.15MoSe/BiVO 复合材料对草甘膦的降解表现出最高的光催化性能，并且在光催化反应中表现出高稳定性和良好的可重复使用性。
