The MoS₂ quantum dots less than 10 nm were in situ prepared in green ILs for the first time. The MoS₂ quantum dots can be easily obtained by simple one-step synthesis within the preparation of ILs themselves. The physico-chemical and tribological properties of the acquired the MoS₂ QDs in ILs were systematically studied. Compared with pure ILs, the MoS₂ QDs in ILs exhibiting long-term dispersion stabilities have superior lubricating properties under harsh conditions. Thin films formed according to the XPS results were attributed to be the main account for the preferable tribological properties of the MoS₂ QDs in ILs than pure ILs.

一步制备含MoS 2量子点的绿色IL的摩擦学性能

首次在绿色IL中原位制备了小于10 nm的MoS ₂量子点。在IL本身的制备过程中，可以通过简单的一步合成轻松获得MoS ₂量子点。系统研究了获得的ILS中的MoS ₂ QD的理化性质和摩擦学性质。与纯离子液体相比，具有长期分散稳定性的离子液体中的MoS ₂ QD在苛刻条件下具有优异的润滑性能。根据XPS结果形成的薄膜被认为是IL中MoS ₂ QD的摩擦学性能优于纯IL的主要原因。
