压电-光催化协同下花球状MoS_(2)对丁基钾黄药降解性能研究

Synergetic Piezoelectric-photocatalysis of Flower Globular MoS_(2) for Degradation of Butyl Potassium Xanthate

以聚乙二醇为交联剂,硫脲和四水钼酸铵为原料,采用水热法合成了花球状MoS_(2)。通过X射线粉末衍射、扫描电子显微镜、紫外吸收光谱等分析方法对所制备MoS_(2)的形貌和结构进行分析。在300 W氙灯(420 nm紫外滤光片)与超声条件下,研究MoS_(2)对丁基钾黄药的压电-光催化降解性能。结果表明,MoS_(2)为花球状结构,对丁基钾黄药的压电-光催化降解性能优于光催化和压电催化降解性能。当降解时间10 min,MoS_(2)对丁基钾黄药的压电-光催化降解率达到99.45%。

Using polyethylene glycol as the cross-linking agent, thiourea and ammonium molybdate tetrahydrate as raw materials, the flower globular MoS_(2)was synthesized by hydrothermal method. The morphology and structure of the prepared MoS_(2)were analyzed by X-ray powder diffraction, scanning electron microscopy, ultraviolet absorption spectroscopy and other analytical methods. Under the conditions of 300 W xenon lamp(420 nm ultraviolet filter) and ultrasound, the piezoelectric-photocatalytic degradation performance of MoS_(2)on butyl potassium xanthate was studied. The results show that MoS_(2)has a flower globular structure, and the piezoelectric-photocatalytic degradation performance of butyl potassium xanthate is better than the photocatalytic and piezoelectric catalytic performance, respectively. When the degradation time was 10 minutes, the piezoelectric-photocatalytic degradation efficiency of MoS_(2)on butyl potassium xanthate reached 99.45%.
