> The team showed that as the catalyst brought the hydrogen and oxygen together to form hydrogen peroxide, it simultaneously produced a number of highly reactive compounds, known as reactive oxygen species (ROS), which the team demonstrated were responsible for the antibacterial and antiviral effect, and not the hydrogen peroxide itself.
> The catalyst-based method was shown to be 10,000,000 times more potent at killing the bacteria than an equivalent amount of the industrial hydrogen peroxide, and over 100,000,000 times more effective than chlorination, under equivalent conditions.
Basically, I'm getting the highly reactive ROS are the key point here, they're creating them in situ so they're able to be exploited where as standing h2o2 is likely much less reactive.
The order of magnitude gains are easy to grasp if you take into consideration the literal hours you need to wait for chlorine or similar to sterilize water. If there is a way to speed that up to near instant your gains are going to be relatively immeasurable.

- engineer_22 5y agoCl cant kill Giardia oocysts, they have to be filtered out.
- slownews45 5y agoChlorine is effective against Giardia. It requires longer exposure periods generally and can be temp dependent (ie, 1 hr vs 1 minute).
- engineer_22 5y agoYes, that's right. Cryptosporidium, another common parasite, is much more resistant to Chlorine
