二硫化钼自组装微球的制备及其吸附性能

Preparation and Adsorption Properties of Molybdenum Disulfide Self-Assembled Microspheres

利用微波辅助水热法合成了二硫化钼(MoS_(2))样品,并对其进行了形貌、结构、吸附性能等研究,结果表明:在有CTAB存在的生长条件下,MoS_(2)纳米片可以通过自组装形成表面多孔隙的中空微球结构;而在无CTAB存在的情况下,得到的样品为MoS_(2)纳米片的无序堆叠。利用亚甲基蓝(MB)溶液对2种MoS_(2)吸附性能测试结果表明:0.04 g MoS_(2)纳米片10 min吸附量为32.42 mg/g,而0.03 g MoS_(2)自组装微球10 min吸附量即可达到38.15 mg/g,显示出了更好的吸附效果。

Molybdenum disulfide(MoS_(2))is synthesized by microwave-assisted hydrothermal method,and the morphology,structure and adsorption properties of MoS_(2)are studied.The results show that under the growth condition with CTAB,MoS_(2)nanometer sheets can form hollow microsphere structures with multi-pores on the surface by self-assembly.In the absence of CTAB,the obtained samples are disorderly stacked MoS_(2)nanometers.The adsorption performance test results of two kinds of MoS_(2)show that whereas the 10-minute adsorption capacity of 0.04 g MoS_(2)nanometer tablets is 32.42 mg/g,the 10-minute adsorption capacity of 0.03 g MoS_(2)selfassembled microspheres can reach 38.15 mg/g,showing a better adsorption effect.
