Developing solar evaporators with high water production rates has become the core challenge and cutting-edge direction in the field of solar desalination. This dataset provides a comprehensive introduction to nickel-based 3D surface plasmonic evaporators. It includes preparation data of the evaporators, where 3D printing technology is used to combine surface plasmonic nanoparticles with hierarchical porous templates. It also covers characterization data: the morphology, crystal structure and light absorption of the evaporators were characterized using scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffractometer (XRD) and UV-Vis spectrophotometer equipped with an integrating sphere. This dataset includes mass transfer flux data: the hydrophilicity of the evaporators was characterized using contact angle goniometer and X-ray photoelectron spectroscopy (XPS); the mass transfer flux of the evaporators was tested, and the relationship between their microstructure and mass transfer flux was analyzed. It also contains evaporation performance data: the evaporation rates of the evaporators under different light intensities were tested using a xenon lamp and analytical balance (2.08 kg·m⁻²·h⁻¹ under 1 sun; 43.45 kg·m⁻²·h⁻¹ under 20 suns), and the corresponding photothermal conversion efficiency was calculated (91.13% under 20 suns). Furthermore, it includes water production performance data: the water production rate of the evaporators was tested using a self-made water production device (29.09 L·m⁻²·h⁻¹), and their treatment capabilities for salinity variation, heavy metal ions and organic matter were further characterized. This dataset provides theoretical and experimental data support for the development of high water production rate solar evaporators in China.
