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.

A residue-free approach to water disinfection using catalytic in situ generation of reactive oxygen species - Nature Catalysis

Despite its biocidal properties, the use of hydrogen peroxide is still limited in the context of water disinfection. Here an approach is disclosed based on the

Here, we show that the reactive oxygen species—which include hydroxyl, hydroperoxyl and superoxide radicals—formed over a AuPd catalyst during the synthesis of hydrogen peroxide from hydrogen and air are over 107 times more potent than an equivalent amount of preformed hydrogen peroxide and over 108 times more effective than chlorination under equivalent conditions.

凄い研究のようですが「1000万倍」は盛りすぎのように思えます。
まあ、何を対象にするかによるのでしょうが…。
