“…There are only a few reports on phosphorene/antimonene‐based photothermal evaporation. The efficient photothermal conversion makes them advantageous for photothermal evaporation, but their photo‐degradability should be considered for practical applications. There have been a vast number of strategies working on enhancing the stability of phosphorene, including covalent bonding via aryl diazonium, surface coordination of titanium sulfonate ligand, fluorination, alkali metal‐intercalation, metal‐ion passivation, and package by graphene shell, hexagonal BN, organic monolayers, graphene oxide (GO), AlO x , etc.…”
