Zusammenfassung:The invention discloses a copper-containing carbon-based composite efficient photothermal conversion material and a preparation method thereof. An adsorbent is prepared from a chitin derivative, and after copper ions are adsorbed, the copper-containing carbon-based composite efficient photothermal conversion material is obtained through carbonization treatment. According to the method, copper ions in copper-containing waste liquid are treated by utilizing an adsorption method and are reused, so that the recycling of wastes is effectively realized, and the problems of complex preparation and high cost of the current photo-thermal conversion material are effectively solved. Efficient light absorption is realized through waste utilization, and the material has a wide application prospect. Meanwhile, in the field of solar heat utilization, cellulose polyacrylamide hydrogel is prepared, the hydrogel can be cut into any shape and has a good porous structure and floating performance, the evaporation rate of the hydr
