| description | Photocatalytic technology is widely used in water purification because of its environmental protection, high efficiency and energy saving. Therefore, it is extremely important for the selection and preparation of specific semiconductor materials used in the field of photocatalysis. In this work, 1T@2H MoS2 nanosheets were fabricated by simple hydrothermal method, and the photocatalytic property of as-prepared 1T@2H MoS2 were investigated by the photo-degradation of methylene blue (MB) water solutions under visible light irradiation via 2H MoS2.The results indicated that compared to 2H MoS2, the 1T@2H MoS2 exhibited more excellent photocatalytic degradation property. After 150 minutes of irradiation under visible light, 1T@2H MoS2 had a removal rate of 98% for MB, and 2H MoS2 eventually reached 19%. The enhancement photocatalytic property of 1T@2H MoS2 could be attributed to the reduced band gap energy of the hybrid-nanosheets and the increased in electron migration speed. |
