Desert areas have broad application prospects.

Description

technical field [0001] The invention relates to the technical field of air-based water production, in particular to a preparation method of a solar-assisted air-based water production material and its product and application. Background technique [0002] The shortage of water resources, especially the shortage of fresh water resources in inland areas, is an important factor restricting the further development of social economy. Although some mature water purification technologies (such as reverse osmosis and multi-stage flash evaporation) have made great progress, the inland These technologies are difficult to implement in regions due to their remoteness from the ocean or lack of natural water sources. As a part of the global fresh water resources, the atmosphere is estimated to hold about 10% of the global fresh water resources, which mainly exist in the state of water vapor or mist, so how to capture this water from the air and convert it into drinkable fresh water gradua...
