Abstract

Abstract

In order to alleviate the shortage of freshwater resources,a 2-dimensional MoS₂/bamboo photothermal conversion material was prepared by hydrothermal synthesis of molybdenum disulfide on bamboo with sodium molybdate and thiourea as raw materials. Its desalination property was examined through the seawater evaporation test. The results showed that the evaporation rate of seawater with MoS₂/bamboo reached 1.095 kg m^-2·h^-1 after one-hour evaporation under one-sun intensity illumination. The light-heat conversion efficiency was 78.20%. And the maximum optical absorptivity of MoS₂/bamboo at wavelengths between 250 nm and 2 500 nm measured by UV/Vis/NIR diffuse reflectance spectroscopy exceeded 80%. These indicated that MoS₂/bamboo material boasted good photothermal conversion efficiency. Therefore,MoS₂/bamboo material in this study had superior photothermal water evaporation performance,which provided reference and application basis for realizing the efficient utilization of green and sustainable photothermal evaporation devices.
