Enhanced photocatalytic performance and stability of 1T MoS2 transformed from 2H MoS2 via Li intercalation

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...
