Abstract

Interfacial solar steam generation (ISSG) off ers a sustainable and environmentally friendly strategy for addressing the energy

and water crises. In this study, we fabricated a highly effi cient and cost-eff ective plasmonic photoabsorber for ISSG of

seawater by coating silver nanoparticles (Ag NPs) on pinecone (PC). The PC with low thermal conductivity and numerous

aligned microchannels for fast water transport, provides suffi cient water supply and reduces the bulk heat loss. In addition,

Ag NPs strongly absorb solar radiation through the surface plasmon resonance eff ect. Using Ag/PC under 1 sun (1 kW m –2 ),

we achieved an evaporation fl ux and effi ciency of 1.82 kg m –2 h –1 and 100%, respectively. Moreover, Ag/PC removed more

than 99% of Na + , K + , Mg 2+ , and Ca 2+ ions from seawater. The plasmonic PC also exhibited excellent cycling during 10

cycles effi ciency of ISSG. Furthermore, treatment of paper industry wastewater with Ag/PC resulted in a signifi cant decrease

in the concentration of ions.
