Synthesis of nanosized ultrathin MoS2 on montmorillonite nanosheets by CVD method

As an emerging material, exfoliated molybdenum disulfide (MoS 2 ) has an excellent performance in catalysis, electronics and adsorption. However, the application performance of exfoliated MoS 2 is limited by the strong adhesion between MoS 2 layers and the low colloidal stability of MoS 2 in water. In this study, for the first time, nanosized ultrathin MoS 2 was successfully synthesized on exfoliated montmorillonite (MMT) by CVD method. Two reaction mechanisms were found when using flow gas with or without H 2 . The introduction of H 2 promotes the growth of MoS 2 crystals and reduces nucleation density. The MoS 2 /MMT showed excellent performance in dye degradation.
