Abstract Solar‐thermal water evaporation, as a promising method for clean production, has attracted increasing attention. However, solar evaporators that exhibit both high vapor generation ability and anti‐oil‐fouling have not been reported. Here, unique metal–organic‐framework‐based hierarchical structure, referred to MOF‐based structure (MHS), is rationally designed prepared, which simultaneously displays absorption superhydrophilic underwater superoleophobic surface property.
