Ohio researchers create nanotech blankets to purify water

Researchers in Ohio have created a new material that can purify water using sunlight. This innovation could lead to cleaner drinking water by breaking down harmful pollutants. The material consists of tiny fiber-like strips made from titanium dioxide (TiO₂), a compound used in solar technology. The team improved its effectiveness by adding copper, which helps the material absorb light energy more efficiently. This allows it to target and eliminate contaminants in both air and water. The lead researcher, Pelagia-Iren Gouma, noted that these nanomats can float on water and are reusable. They could be particularly useful in developing countries, helping to clean polluted waterways. Unlike traditional solar cells, these nanomats do not produce toxic waste, making them an environmentally friendly option. While the technology is promising, mass production depends on industries adopting it. Researchers are eager to optimize the material further for various applications, including sustainability efforts and solar hydrogen production. The findings were published in the journal Advanced Science, highlighting the potential of this new nanotechnology.
