In order to determine the influence of carbonization on solar absorption and seawater evaporation in biomass materials,porous peach charcoal was prepared with anaerobic high-temperature carbonization of waste peach wood,the chemical characterization and appearance were analyzed,and the solar evaporation performance was tested.The results showed that the material featured ultra-fast water transmission and full-spectrum sunlight absorption capacity,and the absorption rate was 94.84％in the full wavelength range of sunlight(250～2 500 nm).Under one solar irradiation,the seawater evaporation rate of PWC reached 1.56 kg·(m2·h)-1,and the evaporation rate remained above 1.50 kg·(m2·h)-1 after 30 cycle stability tests.
