Integrating high-entropy alloy oxides with porous wood architectures for boosted salt-resistant water evaporation

Solar-driven interfacial desalination technology has recently emerged as a promising way to realize seawater desalination with high energy conversion efficiency.However,salt accumulation on solar absorber surface significantly retards desalination rate,especially for highsalinity seawater.Herein,a vertical Janus-interface saltresistant solar evaporator is constructed for simultaneous efficient solar absorption and stable high-salinity desalination based on the assembly of hydrophilic delignification wood(DW),high-entropy alloy oxides(HEAO),and hydrophobic polydimethylsiloxane(PDMS).
