Abstract Scope Solar-driven interfacial steam generation is considered as a sustainable pathway for clean water generation. However, designing an evaporator that can harvest maximum heat at air-water interface with the minimum usage of photothermal material is still a challenge to this technology. Here, a heterostructure of covellite (CuS) and spherical carbon nanoparticles (CPs) (CPs@CuS) was prepared and selectively confined on the upper surface of polydopamine (PDA) activated polyurethane (PU) foam. With reasonable light absorption and anchoring abilities, the PDA film on PU foam acts as both solar absorber and platform for interactions that enables CPs@CuS to firmly adhere onto foam surface. The CPs@CuS coated foam exhibited an excellent solar absorption of 98.9% leading to surface temperature elevation of 61.6 ℃ upon solar illumination of 1 kW m-2 . Taking merits of the synergistic effect, the coated PU foam demonstrates an evaporation rate of 1.62 kg m−2 h−1 and energy efficiency of 93.8%.
