Abstract

Molybdenum disulfide is a competitive photocatalyst in organic pollutant degradation. 1T MoS ₂ was prepared by Li intercalation from hydrothermal synthesized 2H phase MoS ₂ . The 1T MoS ₂ presents a lager intralayer distance of 12.0 Å compared to that of 6.5 Å in 2H MoS ₂ . A stability of the prepared 1T phase was studied and a complete transformation of 1T to 2H was reached at 120 °C. The addition of nano-Au particle reduce the interlayered interaction in the MoS ₂ lattice. Both 1T@2H-MoS ₂ and 1T@2H-MoS ₂ /Au present high decomposition rate of MB under visible light. 1T@2H-MoS ₂ /Au presents a 90.4% decomposition of the modeling compound MB in 20 min compared to 25.2% MB conversion catalyzed by 2H-MoS ₂ under the same conditions.
