Is there any metal or gas which absorbs carbon dioxide and nitrogen gas?

Answer 1

Mother nature has a way of absorbing carbon dioxide. It's called rain. Rain water combines with carbon dioxide to make carbolic acid. The carbolic acid falls to the earth and combines with rock and dirt to make a soft rock. People down wind of large smokestacks have a problem with the acid rain. Too much acid rain will kill trees. Planet earth does not get enough rain to remove the increasing amounts of carbon dioxide we are putting into the atmosphere. The carbon dioxide we are making adds to the problem of global warming.

　

I have wondered if putting water sprayers into our smokestacks will remove the carbon dioxide making acid water. That acid water can be mixed with soil to make soft rock. The soft rock can be used for landfill. Perhaps we can remove carbon dioxide in our smokestacks before it gets into our atmosphere in this way?

Answer 2

Yes, certain materials like zeolites and activated carbon can adsorb carbon dioxide and nitrogen gas from a mixture. Additionally, metal-organic frameworks (MOFs) have shown potential for selective absorption of carbon dioxide over nitrogen gas.
