Hybrids of graphene and other two-dimensional materials have shown extraordinary properties. However, the current preparation method, chemical vapor deposition, suffers from the disadvantages of low throughput and high cost, and the produced solid hybrids are unsuitable for those applications in aqueous solution. Therefore, it is very important to find a facile method to prepare these hybrids in solution. Here, a hybrid of MoS2 and graphene oxide (GO) (MoS2/GO) is prepared by a one-pot liquid-phase-exfoliation process. The exfoliated MoS2 by ultrasound waves is stabilized by amphiphilic GO in aqueous solution. The size of GO plays an important role in tuning the structure of MoS2/GO. Ultraviolet-visible absorption spectrum, dynamic light scattering, scanning electron microscope, transmission electron microscope and atomic force microscope are used to characterize the structure of MoS2/GO produced by fractional centrifugation after exfoliation of MoS2 in GO suspension. The results indicate that GO is adhered to the surface of MoS2 to stabilize MoS2/GO in solution. Furthermore, this preparation method can also be used to prepare the hybrids of GO and other two-dimensional materials. (C) 2015 Elsevier Ltd. All rights reserved.
