Australian chemists have found a way to use sunlight to purify wastewater faster, cheaper, 15 times more efficient than anything currently on the market - all without the need for ultraviolet light.
Using modified titanium dioxide as a photocatalyst that works with sunlight, the technology is different to other major water purification products on the market - since it doesn't need any UV light.
Research group leader Professor Yun Liu from The Australian National University (ANU) said the team's invention was 15 times more efficient than leading commercialised products.
"With innovative chemistry design, we can use our photocatalyst to purify water with natural sunlight instead of UV light and dramatically reduce costs for operators," said Professor Liu from the ANU Research School of Chemistry.
"Our photocatalyst can completely decompose organic pollutants in wastewater in 20 minutes, compared with the leading commercilised products which take one hour to decompose only 26 per cent of the same pollutants."
The new technology could be useful for treating water for human consumption and has potential applications in making self-cleaning building materials, including glass, and splitting water to make hydrogen fuel.
Photocatalysts can also be used to speed up chemical reactions used in industrial processes in automotive, construction, environmental, medical and other sectors. The team added nitrogen and niobium ions in pairs into the titanium dioxide to improve its performance as a photocatalyst.
"It's an important breakthrough for science and industry," Professor Yun Liu said. "With four years of work done in this area, we now understand the science and can rationally design catalysts."
ANU conducted the research in collaboration with the Chinese Academy of Sciences, the University of New South Wales, Western Sydney University, and the Australian Nuclear Science and Technology Organisation. ANU has filed a provisional patent covering the discovery, which involved the design strategy, chemical composition and manufacturing approach.

chinybelle:Lol...nigeria and scientific research?pull-him-down syndrome/nepotism would never bring our best to light rather we keep being in the news for stuff like where is your certificate, fraud and looting, 328 dead from meningitis, terrorism and.communal clash...the set up is designed to benefit only a few while the rest can kill themselves for some stupid belief
