Construction of carbon nanotubes bridged MoS2/ZnO Z-scheme nanohybrid towards enhanced visible light driven photocatalytic water disinfection and antibacterial activity

We fabricated carbon nanotubes (CNTs) bridged MoS2/ZnO nanohybrids from the hydrothermal process for the heterostructure photocatalysts. The nanohybrids were effectively operated as visible light action for the photocatalytic of organic compounds and heavy metal reduction. The results exhibit that the great photocatalytic efficiency from nanohybrids for the 94.5% of tetracycline (TC) degradation after 60 min of irradiation. Enhanced environmental pollutants removal was due to inhibition in recombination of photogenerated electron-hole pairs. The nanohybrids also displayed better photocatalytic performance and reduction capacity (Cr (VI) ions removal), about 10–15 folds as greater than that of bulk MoS2, and ZnO photocatalysts. The nanohybrid showing a wonderful photocatalytic antibacterial capability of 99.9% towards E. coli after 5 min and supplying a favourable environmentally friendly for water disinfection. Based on this studies, we believe that a promising candidate nanohybrids for the photocatalytic of various water contaminants under visible light activity.
