Three-dimensional (3D) nanocomposite monolith containing MoS2 nanoflakes, graphene oxide (GO) and amorphous SiO2 was fabricated through a simple mixing process and hydrothermal treatment. Compared with GO monolith prepared under identical conditions, the MoS2-GO monolith had larger specific surface area, smaller pore diameter, as well as much higher adsorption capacity for Cu2+ and Rhodamine B. Introducing amorphous SiO2 into the end monolith by using tetraethyl orthosilicate as a reactant in the synthesis reduced shrinkage and produced a greater number of large pores (>1 mu m pore diameter) in the monolith. The specific surface area and pore diameter of the MoS2-GO monolith were 321.4 m(2) g(-1) and 11.71 nm, respectively. The higher adsorption capacity was ascribed to the presence of many S atoms in the MoS2 nanoflakes inside the monolith.
