摘要：

Functionalization of MoS(2)was achieved by treatment in a strongly reducing sodium naphthalene solution. Dodecyl was grafted onto MoS(2)nanosheets using alkyl sulphates as electrophiles to obtain dodecylated MoS(2)without affecting the MoS(2)crystalline structure. Superior electrocatalytic properties are obtained for dodecylated MoS2. The polarisation curve of this nanomaterial remained constant even after 1000 consecutive cycles. This route provides a new pathway for covalent functionalization of MoS(2)and might find a variety of applications, such as electrocatalysts.
