摘 要：In this work, MoS₂@montmorillonite nanosheets hollow microspheres（MoS₂@MMTNS-HMS） with a novel morphology structure was successfully synthesized through loading MoS₂ to the surface of MMTNS-HMS via hydrothermal method. The novel material has been characterized through the measurements of SEM, TEM, Raman spectra and UV–vis absorption spectra. The results have shown that MoS₂@MMTNS-HMS emerges higher light-utilization efficiency, density of edge active sites and separation of photoelectrons, owing to its unique hollow structure, vertically-aligned MoS₂ nanosheets, which greatly enhances its photocatalytic activity. Furthermore, the cycle stability of MoS₂@MMTNS-HMS is much higher than that of pristine MoS₂, which is attributed to that MMTNS-HMS greatly inhibits the oxidation of MoS₂ during photocatalytic. MoS₂@MMTNS-HMS could be a promising photocatalyst for the applications in the elimination of organic pollutants.
