Ultrahigh solar steam generation rate of a vertically aligned reduced graphene oxide foam realized by dynamic compression

Dynamic compression is proven to be an efficient strategy to adjust the water energy state in the channels of V-RGO foams. The V-RGO foam with a compressive strain of 47.1% exhibits a water evaporation rate of 3.39 kg m⁻² h⁻¹ under 1-sun irradiation.
