Lanthanide doped two dimensional heterostructure nanosheets with highly efficient harvest towards solar energy

At present, the shortage of potable water is still a critical issue. The emerging of solar-driven evaporation technique offers a promising way to solve freshwater scarcity. However, developing highly efficient evaporation system is still a challenge. Herein, this work developed two-dimensional heterostructure nanosheets as the photothermal agent. We used the WSe2 nanosheets to enhance the absorption of graphene and facilitate the heat...
