“…The value is much higher than that of all previously reported MXene-based and fabric-based evaporators and the evaporation rate and evaporation efficiency are among the highest of all solar absorbers (Fig. 4f and Table S1) [11,34,36,38,55,[57][58][59][60][61][62]. This result demonstrates the advantage of a honeycomb structure in energy utilization.…”

“…To confirm the phase structure of different HEANPs, X‐ray diffraction (XRD) has been employed (Figure S18, Supporting Information), and the FCC crystal structure of all HEANPs evidences that the different elements are uniformly mixed into a solid solution after the ultrafast‐cooling treatment [33, 34] . It is found that the as‐made nanoparticle is easily oxidized once it has been synthesized, [16] and the surface element distributions tested by X‐ray photoelectron spectroscopy (XPS) prove the uniform dielectric metal oxide shells outside the nanoparticle (Figures S21 to S32, Supporting Information) [35, 36] …”

Photothermal materials with broadband optical absorption and high conversion efficiency are intensively pursued to date. Here, proposing by the d‐d interband transitions, we report an unprecedented high‐entropy alloy FeCoNiTiVCrCu nanoparticles that the energy regions below and above the Fermi level (±4 eV) have been fully filled by the 3d transition metals, which realizes an average absorbance greater than 96 % in the entire solar spectrum (wavelength of 250 to 2500 nm). Furthermore, we also calculated the photothermal conversion efficiency and the evaporation rate towards the steam generation. Due to its pronounced full light capture and ultrafast local heating, our high‐entropy‐alloy nanoparticle‐based solar steam generator has over 98 % efficiency under one sun irradiation, meanwhile enabling a high evaporation rate of 2.26 kg m−2 h−1.

The absorption can reach about ca.…”
