本研究以氧化石墨烯为前驱体,利用钼酸钠和硫脲通过水热法在不同阳离子表面活性剂(C14TAB,C16TAB,C18TAB)的辅助下合成得到MoS2/GF复合结构.XRD和SEM分析表明,MoS2/GF复合材料因阳离子表面活性剂的不同而呈现不同的结构和表面形貌;电化学性能测试表明其结构和表面形貌对电极的容量、循环稳定性和倍率性能都有较大影响.相比于C16TAB和C1 8TAB,C14TAB辅助合成的MoS2/GF复合结构具有最高的首次放电容量(955mAh/g),50次循环后仍保持751 mAh/g的可逆容量,而且倍率性能更好.本研究揭示MoS2/GF复合材料电化学性能的提升可归因于其独特的praticle-on-sheet结构以及MoS2与石墨烯之间的协同作用.
