▎ 摘　　要

NOVELTY - Preparation of self-turning black Quinoa cellulose/graphene oxide aerogel involves (1) extracting Quinoa cellulose, (2) formulating the Quinoa cellulose extract into Quinoa cellulose aqueous dispersion, (3) adding graphene oxide dispersion to the Quinoa cellulose aqueous dispersion, mixing and configuring into multiple composite liquids, ultrasonically mixing the multiple composite liquids, suction filtering into sticky cake, and freeze-drying. USE - Preparation of self-turning black Quinoa cellulose/graphene oxide aerogel for seawater desalination (claimed). ADVANTAGE - The method produces aerogel with excellent self-cleaning performance in seawater desalination. The composite cellulose and graphene oxide to prepare aerogel whose color can change from light brown to dark black under water-light synergistic stimulation. The aerogel used in seawater desalination through the boundary, the evaporation rate reached 3.6 kg m-2hour-1 under a simulated sunlight intensity (1000 Wm-2) irradiation, outdoor experiment continued for 15 days, and the evaporation rates of simulated seawater and distilled water reached 12.6 kg m-2day-1 and 12 kg m-2day-1 respectively. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for use of self-turning black Quinoa cellulose/graphene oxide aerogel for seawater desalination. Under the combined stimulation of light and water, the aerogel will change from light brown to dark black to enhance the absorption of light. In the process of seawater desalination, the crystalline salt accumulated on the surface is self-cleaning in the absence of light or weak light. The weak light condition is that the light is less than 300 Wm-2. The self-cleaning function is specifically in the case of no light or weak light, the crystalline salt accumulated on the surface will dissolve in the seawater source under the action of chemical potential for 30-240 minutes.
