Photothermal Water Evaporation via Hollow-CuS Embedded PDMS Sponge Under UV, Visible, and IR Irradiation
Abstract
Photothermally-based solar steam generation has emerged as a promising solution for effi cient water evaporation. Photothermal
particles off er signifi cant advantages in water treatment by converting light energy into heat. While gold nanoparticles
(AuNPs) are commonly used, their cost can be prohibitive. This study focuses on developing a photothermal water evaporation
matrix using hollow CuS nanoparticles (NPs)-embedded in a polydimethylsiloxane sponge. This innovative approach
enhanced both water absorption and heat transfer. The system achieved a remarkably high water evaporation rate of 3.23 kg/
m 2 h under xenon arc lamp irradiation. The investigation revealed that specifi c wavelength ranges, particularly the ultraviolet
(UV) and infrared regions, signifi cantly contribute to water evaporation, with the UV region playing the most prominent
role. These fi ndings help optimize photothermal eff ects by enhancing light absorption at specifi c wavelengths. Notably, CuS
NPs off er a cost-eff ective alternative to AuNPs.
