So... these are very fun materials, a kind of real-life menger sponges with huge internal surface area.
Some fifteen years ago, as an intern working for a company making desulfurization catalysts (stuff that removes nasty sulfur compounds from crude oil so they don't stink up the gas you put in your car), I prepared a few of the easy-to-handle air stable ones.
Reactions between fluids and a solid catalyst take place on the catalyst surface, so higher surface area = higher reaction rates = better.
I remember everyone's minds at the company being completely blown by the ridiculous surface areas of my attempts at recreating some random MOFs from literature. Got awarded the highest possible grade for no reason other than (badly) following a few procedures and measuring that indeed, their internal surface area was insanely big.
Thanks Yaghi and co. I'll always fondly remember your MOFs.

- mikeyouse 1y agoOP was an intern - the potential commercialization of the tech would be left up to the rest of the team. And "costly" is a very relative term.. Exxon earned like $350 billion in revenue last year with over $30 billion in profit. They'd be happy to invest in cutting edge tech if it simplifies their supply chain or removes some steps or units from their refining process.
- condensedcrab 1y agoIANAL, but I suspect that the IP situation is similar to current uses, such as catalytic converters. New tech and specific applications can be covered for commercialization, but the general "idea" of using MOFs for adsorption is broad enough that you'd probably only get into legal hot water if you tried to introduce a direct competitor to someone in the market.
- isoprophlex 1y agoIn addition to what condensedcrab and mikeyouse wrote, there is a HUGE gap between a commercially viable, patentable product and a freely accessible paper stating "take copper acetate and benzenetricarboxylic acid, stir at pH so and so and remove the volatiles in vacuum". The resulting blue crunchy mess is NOWHERE near something on a support material that you throw into a fluidized bed reactor for reaction at elevated temperature for months on end. And that's where the proprietary magic happens.
- throwawaymaths 1y agois desulfurization endothermic? one thing I'd worry about when increasing the surface area that much for an industrialized process is making your reaction vat into a bomb
