You may recall the Apollo 13 disaster, if not watch the movie. Due to CO2 building up in the cabin to dangerous levels, the crew on the ground devised a filtering system made with duct tape and plastic tubing to bubble the cabin air through LiOH to remove CO2....it was a life saver....
Yes but the clever thing was not that they used LiOH to filter/scrub the air.

The clever thing was to get around what some might consider an engineering goof.

"Goof" because one would expect all similar components on a space craft to be standardized/interchangeable.

The space craft already had LiOH scrubbers to get rid of the CO2.

But there were not enough available and the cartridges they had were for another part.

Different shapes, what they had didn't fit into they scrubber machine - so the clever thing that they did was to make cartridge adapter to the different system.

In other words they made an adapter. Clever and allowed them to survive.

But it's not like they had some LiOH handy and figured out that they could use it to bring CO2 down to safe levels - it was part of the design of the craft.
