? 2022 Elsevier B.V.The pollution of heavy metals in aqueous solution has been paid considerable attention in the past several decades. Many researches focused on developing new materials or methods for removing heavy metals. The two-dimensional lamellar structure of molybdenum disulfide (MoS2) has attracted extensive interest and was regarded as a potential material due to it has a large number of active sites. In this paper, a novel one-step hydrothermal method was proposed to prepare the MoS2/Bentonite composite material. The MoS2 composed of many nano petals grew successfully in the pores of bentonite to form flower spheres, and the addition of bentonite can effectively avoid the agglomeration phenomenon of MoS2 prepared by the hydrothermal method. Pseudo-second-order model was applied to describe the adsorption process, revealing the adsorption dominated by chemical adsorption. The dynamic model was in accord with the Langmuir model and the maximum adsorption capacity of Cd2+ was 89.45 mg/g. The excellent performance of MoS2/Bentonite made it have the tremendous application of removing heavy metal ions.
