Titanium dioxide nanoparticles ‘decorated’ with gold absorb about 96% of the solar spectrum and turn it into heat, said the researchers from the Far Eastern Federal University, Itmo University and the Far Eastern Branch of the Russian Academy of Sciences, who worked with colleagues from Spain, Japan, Bulgaria, and Belarus to develop and test the material. It could make evaporation in desalination plants up to 2.5-times quicker, while also tracking hazardous molecules and compounds.

Titanium dioxide nanoparticles decorated by gold absorb about 96% of the solar spectrum and turn it into heat. The material can accelerate the evaporation in desalination plants up to 2.5 times and can track hazardous molecules and compounds. An international research team with representatives from Far Eastern Federal University (FEFU), ITMO University, and the Far Eastern Branch of the Russian Academy of Sciences, published a related article in
ACS Applied Materials and Interfaces.
Access to safe water is included in the 17 UN Sustainable Development Goals. Meanwhile, the World Health Organization (WHO), and the Children s Fund (UNICEF) addressed the problem in 2019 report, noting that 2.2 billion people lack access to safe drinking water.
