Herein, a bimetallic functional hollow nanoreactor defined as (Co@SiO2/Cu‐X) was successfully constructed and endowed with a hollow configuration composed of mesoporous N‐doping C‐Silica hybrid shell encapsulated ultrafine Cu and Co metallic species. Such a configuration allows for the efficient diffusion and open reaction space of big contaminant molecules. The catalytic synergy of exposed Co‐Cu bimetals and the easy accessibility of electron‐rich contaminants by polar N doping sites triggered surface affinity make the optimal Co@SiO2/Cu‐6 afford an excellent catalytic norfloxacin mineralization activity (7 min, kabs=0.744 min‐1) compared to Cu‐free Co@SiO2‐6 (kabs=0.493 min‐1) and Co‐6 (kabs=0.378 min‐1) Benefiting from the above unique advantages, Co@SiO2/Cu‐6 show excellent removal performance in degrading different pollutants (carbamazepine, oxytetracycline, tetracycline, and bisphenol A) and persistent recycled stability in removing NFX. In addition, by virtue of the excellent photothermal properties, interfacial solar water evaporation application by Co@SiO2/Cu‐6 was further explored to reach the regeneration of cleanwater (1.595 kg m‐2 h‐1, 97.51%). The integration of pollutant mineralization and solar water evaporation by creating the monolith evaporation by anchoring the Co@SiO2/Cu‐6 onto the tailored melamine sponge allows the regeneration of cleanwater (1.6 kg·m‐2·h‐1) and synchronous pollutant removal (NFX, 95%, 60 min), which provides potential possibility the treatment of complicated wastewater.

“…20,21 They have achieved considerable development in recent years, mainly based on metallic nanostructures, inorganic semiconductor materials, polymeric materials, and carbo-based materials. 22–32 Metals such as gold (Au), silver (Ag), aluminum (Al), copper (Cu) and palladium (Pd) in the form of nanoparticles or composites have a local surface plasmon resonance effect to produce solar-thermal conversion. Thus, they have been applied widely in solar-driven water evaporation.…”

“…Recently, several state-of-art evaporators have been developed to achieve the goal of antisalt accumulation and improve the evaporation rates: − for example, by constructing a hydrophobic surface to avoid the salt adhering or using some unique materials and structures to selectively block the salt but allow the water to flow through the channels . Despite intensive efforts to design salt rejection by solar interfacial evaporation, challenges still remain in the design of evaporators with both high salt rejection capacity and efficient evaporation performance.…”

Solar-powered steam generation equipment has experienced considerable advancement in recent years as it offers a cleaner and greener method for freshwater production. However, the devices always suffer from a complicated process, high cost, and salt accumulation, which hinder their further application. Here, inspired by the water lily, a highly efficient and antisalt accumulation interfacial solar-driven steam generation device was designed by using the tannic acid–Fe3+ complex as photothermal material. The designed evaporator could be quickly unfolded within 24 s after being irradiated with light and then produce fresh water. It folded within 10 s and then sank into water for removing the accumulated salt after removing the irradiation sources. In addition, the tannic acid–Fe3+ complex on the evaporator surface and the angle of the evaporator allowed light to be reflected several times within the evaporator, effectively increasing the solar energy conversion efficient (2.22 kg/(m2·h)), and apparently, the overall evaporation efficiency of 139.18% was achieved under 1 sun illumination. Moreover, it exhibited an extraordinary antisalt accumulation capacity (by working continuously for 7 days in 10 wt % saline water and 80% reduction in salt accumulation) as well as a low price ($ 1.11/m2). This design would provide a strategy to prepare an antisalt accumulation solar steam devices.
