Photocatalytically reactive surfaces for simultaneous water harvesting and treatment

R. Ghosh, A. Baut, et al.

This innovative research conducted by Ritwick Ghosh, Adrien Baut, Giorgio Belleri, Michael Kappl, Hans-Jürgen Butt, and Thomas M. Schutzius unveils a cutting-edge system that captures fog and cleans organic pollutants simultaneously. Utilizing sunlight-activated TiO2 nanoparticles on a specialized wire mesh, this solution not only addresses water scarcity but does so without requiring energy. Discover how outdoor tests reveal impressive water treatment efficiencies exceeding 85%.

Abstract
This paper demonstrates a system that efficiently captures fog while simultaneously degrading organic pollutants. A wire mesh coated with TiO2 nanoparticles embedded in a polymer matrix acts as the core. Sunlight activates the TiO2, decomposing organic molecules. The mesh's wettability is engineered for enhanced water extraction. Outdoor tests show good fog harvesting and >85% water treatment efficiency, offering an energy-free solution to water scarcity.
