Abstract: Broadband absorbing materials are very conducive in solar steam generation.In this work,Ag@Ag2S/C photothermal conversion materials with porous structure were prepared through freeze casting with Ag@Ag2S nanoparticles and carboxymethyl cellulose as raw materials. The Ag@Ag2S/C photothermal conversion materials can absorb 93% of the solar irradiation and a solar steam generation efficiency of 815% can be achieved under onesun illumination.
Key words: solar energy; photothermal conversion; broad band; water evaporation
