摘要

以钼酸钠为钼源、硫脲为硫源,采用水热法制备二硫化钼/还原氧化石墨烯(MoS2/rGO)复合材料,利用X射线衍射仪、扫描电子显微镜、傅里叶变换红外光谱仪等对复合材料进行表征和分析,通过有机染料罗丹明B(RhB)的光降解实验评价了复合材料的光催化性能。结果表明:在反应时间16h、反应温度220℃、活性组分钼酸钠和硫脲含量为1.5mmol和3mmol的条件下,光照100min后MoS2/rGO复合材料对RhB降解率达到99.33%,相比MoS2降解率有较大提高。这主要是由于石墨烯作为载体提供了更大的比表面积,暴露了更多的催化活性中心,有利于复合材料中光生电子和空穴的有效转移和快速分离。

Abstract

MoS2/rGO composites were prepared by hydrothermal method with sodium molybdate as molybdenum source and thiourea as sulfur source.The catalysts were characterized and analyzed by XRD,SEM and FT-IR.The photocatalytic performance for organic dye Rhodamine B(RhB) was evaluated by photodegradation experiments.The results showed that under the conditions of 16h reaction time,220℃ reaction temperature,1.5mmol of sodium molybdate and 3 mmol of thiourea active component,the degradation rate of RhB by the MoS2/rGO composites could reach 99.33% after 100min illumination,which was higher than that of MoS2.This was mainly due to the larger specific surface area provided by graphene as a carrier,exposing more catalytic active centers,which was conducive to the efficient transfer and rapid separation of photogenerated electrons and holes in the composite.
