Is that much of a problem for a catalyst? Presumably you do not need many of these: at water treatment plants and at the waste-stream for manufacturing processes which emit PFAS. You might not be able to justify the expense inside your home water purification system, but it could still be cost effective for large scale installations.
- momoschili 1y agoit depends on the scale and the required amounts. If having a limited amount of catalyst wasn't such a big problem I suspect hydrogen power would have been much more economically viable.
- ambicapter 1y agoI thought the point of catalysts was that they don't get used up in the reaction they promote.
- djtango 1y agoThe real world is messy - catalysts gradually need replacement over time in non lab conditions https://en.m.wikipedia.org/wiki/Catalyst_poisoning https://en.m.wikipedia.org/wiki/Catalyst_poisoning
- lazide 1y agoThe issue with hydrogen is the source of hydrogen.
- throwup238 1y agoYou would need a lot of catalyst because the water infrastructure to supply several hundred million people in the US is massive, let alone the rest of the world. The problem with those catalysts is that the latter two are minor components of platinum and copper/nickel ores and despite how expensive they are, the extraction is only economically viable as part of other mining. Their supply can only grow as much as platinum extraction allows and demand is already pretty significant with environmental regulations often necessitating their use. Any more demand for them will cause their prices to rise dramatically and its a long way before they become profitable enough to mine on their own (flooding the platinum market in the process which has much higher yields from the ores).
