Abstract

The invention belongs to the technical field of functional nano materials, and particularly relates to a 1T / 2H mixed-phase molybdenum disulfide material as well as a preparation method and applicationthereof. The invention provides a 1T / 2H mixed-phase molybdenum disulfide material. The 1T / 2H mixed-phase molybdenum disulfide material comprises a substrate and a 1T / 2H mixed-phase molybdenum disulfide layer on the surface of the substrate. The 1T / 2H mixed-phase molybdenum disulfide material has high phase transition temperature and low energy band gap, is stable and can achieve efficient full-spectrum solar energy absorption. Experimental results show that the 1T / 2H mixed-phase molybdenum disulfide material forms local heat on a water vapor interface, the efficient solar vapor evaporation rate is 1.52 kg / m<2>*h; compared with a 2H-phase molybdenum disulfide material, the evaporation efficiency of the 1T / 2H mixed-phase molybdenum disulfide material is improved by 20%.

Description

technical field

[0001] The invention belongs to the technical field of functional nanometer materials, and in particular relates to a 1T / 2H mixed-phase molybdenum disulfide material and its preparation method and application. Background technique

[0002] With the increasing utilization and unreasonable waste, the shortage of fresh water resources is becoming more and more obvious. Because solar energy is rich, clean, and non-polluting, solar steam technology has become an effective method to solve this problem. Among them, localized solar steam technology uses local heating of photothermal materials to evaporate water at the gas-liquid interface, reducing the Due to the heat loss associated with heating the entire water body, high-efficiency steam reforming is achieved, which has the advantage of low energy consumption and has attracted widespread attention.

[0003] Efficient photothermal materials are the basis for localized solar steam. Materials widely used in localiz...
