A hydrophilic carbon foam/molybdenum disulfide composite as a self-floating solar evaporator.

Solar-driven interfacial evaporation has gained increasing attention as an emerging and sustainable technology for wastewater treatment and desalinization. The carbon/molybdenum disulfide (C/MoS) composite has attracted more attention due to its outstanding light absorption capability and optoelectronic properties as a solar steam generator. However, the hydrophobic nature of carbon and MoS-based materials hinders their wettability, which is crucial to the effective and facile operation of a solar generator of steam.
