Abstract

Solar steam generation, as a high efficient photo-thermal conversion pattern, has widespread applications, including in wastewater treatment, seawater desalination, and clean water production. However, the lower steam generation efficiency impedes its development. In present study, graphene with better thermal conductivity and light absorption was prepared successfully. Its stability in nanofluid was verified, implying the suitable for photo-thermal conversion. And it was found that the steam amount, evaporation rate and efficiency all increased with the increase of graphene concentrations in the solar steam generation experiment.
