![]() However, with the rapid growth of the human population and industrialization, water pollution is becoming more severe, and several organic compounds with high toxicity in water bodies, even at trace levels, can be harmful to human life. The developed substrate can be an improved and suitable candidate for fresh water production and qualification.Ĭlean water is one of the most important components of life worldwide. The purified water was then analyzed with SERS to confirm its purity. To demonstrate dual-functional properties, the contaminated water was analyzed with SERS and purified by STS. ![]() Enriched SERS hotspots between AuNPs endow the substrates with the ability to detect chemical contamination in water with ppb limits of detection for rhodamine 6G dye and melamine. The STS generation of the substrate is stable during 30 h continuous operation. h −1 under 1-sun illumination, room temperature of 20 ☌, and relative humidity of 40%. ![]() The substrates exhibit 90% of broadband solar absorption between 3 nm and achieve an evaporation rate of 0.96 kg Herein, a simple in situ method is introduced to fabricate Au nanoparticles (AuNPs) on cellulose filter papers as dual-functional substrates for STS generation and surface-enhanced Raman spectroscopy (SERS) sensing. Solar-to-steam (STS) generation based on plasmonic materials has attracted significant attention as a green method for producing fresh water.
