Abstract
Ni<sub>1</sub>Co<sub>3</sub>@PDA nanosheets were utilized as photothermal materials in a kerosene lamp-like evaporator for solar steam generation. A high evaporation rate of 2.42 kg m<sup>−2</sup> h<sup>−1</sup> with a corresponding energy efficiency beyond the theoretical limit was achieved.
