The study on “Solar Water Distillation Technology Using Antibacterial Light-absorbing Textile” by Shougo Higashi, et.al was published in the ACS Applied Materials & Interfaces.
Solar distillation, in which water is distilled using the sunlight to obtain pure water, is gaining considerable attention recently. To enable solar distillation under intermittent sunlight, a light absorber that swiftly converts light into heat is required.
This study produces ultra-lightweight textile using interconnected Ag and Cu2O nanoparticles to achieve broadband optical absorption. Using this textile, an unprecedentedly rapid temperature increase due to solar irradiation was achieved. A major drawback of the solar distillation technology is that if the water contains bacteria, the bacteria will also be contained in the steam. However, as the textile contains Ag, it exhibits antibacterial activity against Staphylococcus aureus and Streptococcus pneumoniae during the water treatment. Therefore, the solar distillation technology using the produced textile is expected to reduce the risk of contamination of water vapor with bacteria as well as post-treatment costs.
