Solar-powered interfacial steam generation (ISSG) has been extensively researched and implemented due to its considerable potential for the cost-effective environmentally sustainable production of purified water. However, substantial energy requirements phase change processes in water evaporation, along with limited light absorption spectrum photothermal materials seriously impede further effective deployment ISSG. Here, a sponge-like CuO/ZnO-PVA/PSS hydrogel (CZO-HH) was prepared by incorporating CuO/ZnO (CZO) heterojunction nanoparticles, known their excellent properties, into poly(vinyl alcohol) (PVA) polystyrene sulfonic acid (PSS) self-assembled interpenetrating double-network hydrogel. Surprisingly, CZO-HH identified novel integration between nonradiative relaxation effect semiconductor unique structural properties hydrogels. This synergistic function leads decrease enthalpy evaporation regulating hydrogen bonding network water, thereby achieving an enhanced rate. Moreover, existence PVA/PSS broadens optical CZO nanoparticles encompass full spectrum, while simultaneously enhancing thermal management capability capabilities conversion. Consequently, had observed achieve maximum rate 2.35 kg·m–2·h–1 efficiency 95.28% under 1-sun irradiation. Furthermore, CZO-PVA/PSS demonstrated capacity wastewater seawater desalination, significant number –SO3H groups within PSS exhibited self-cleaning performance, highlighting long-term practical applications. Therefore, this work reveals importance mass transfer process solar utilization enhance conversion provides technical support next step large-scale promotion desalination.
