Abstract
Description
technical field
[0001] This application is in the field of light conversion. Specifically, the present application relates to graphene-based light-to-heat conversion materials, preparation methods and applications thereof. Background technique
[0002] Water is one of the most abundant chemical compounds on earth. About three-quarters of the world is covered with water, but 97% of the world's water is difficult to use directly in the ocean, resulting in a shortage of fresh water resources. With the development of economy and society, energy consumption is increasing day by day, and environmental pollution damages water resources, leading to an increasing shortage of fresh water resources on the earth. Scientists predict that by 2025, two-thirds of the world's population will face fresh water scarcity. my country has also been listed by the United Nations as one of the 13 water-deficient countries, which will seriously affect the implementation of the sustainable developme...
