Efficient “Core–Shell” Carbon‐Based Solar Evaporator with Honeycomb Structure for Large‐Scale Solar‐Driven Water Purification and Energy Harvesting

Abstract Solar‐driven interfacial water evaporation holds a broad application prospect in the domain of seawater desalination. However, traditional interfacial desalination technology is facing the challenge of large‐scale preparation and desalting performance. Herein, based on the easy processing and low cost advantages of carbon‐based solar‐thermal materials, the study proposes a novel strategy to use the surfactant Pluronic F127 to encapsulate the carbon black to form a size‐stable “core–shell” nanomicelle. Then, the solar‐thermal evaporator cross‐linked by nanomicelle and polyvinyl alcohol is constructed with a surface patterned design inspired by the honeycomb structures, which proved that the evaporator…
