Instant water cleaning method millions of times' better than commercial approach:
A water disinfectant created on the spot using just hydrogen and the air around us is millions of times more effective at killing viruses and bacteria than traditional commercial methods, according to scientists from Cardiff University.
[...] Their new method works by using a catalyst made from gold and palladium that takes in hydrogen and oxygen to form hydrogen peroxide - a commonly used disinfectant that is currently produced on an industrial scale.
Over four million tonnes of hydrogen peroxide are made in factories each year, where it is then transported to the places it is used and stored. This means that stabilising chemicals are often added to the solutions during the production process to stop it degrading but these reduce its effectiveness as a disinfectant.
Another common approach to disinfecting water is the addition of chlorine; however, it has been shown that chlorine can react with naturally occurring compounds in water to form compounds which, in high doses, can be toxic to humans.
