Enhanced photocatalytic performance and stability of 1T MoS2 transformed from 2H MoS2 via Li intercalation
Molybdenum disulfide is a competitive photocatalyst in organic pollutant degradation. 1T MoS2 was prepared by Li intercalation from hydrothermal synthesized 2H phase MoS2. The 1T MoS2 presents a lager intralayer distance of 12.0 Å compared to that of 6.5 Å in 2H MoS2. A stability of the prepared 1T...
