Converting carbon dioxide into oxygen and producing fuels, fertilizers on the red planet using a plasma-based method. A plasma-based way to produce and separate oxygen within the Martian environment has been devised by an international team of researchers. It's a complementary approach to NASA's
There are two big hurdles that stand in the way of producing oxygen on Mars.
“First, the decomposition of carbon dioxide molecules to extract oxygen. It’s a very difficult molecule to break,” said author Vasco Guerra, of the University of Lisbon. “Second, the separation of the produced oxygen from a gas mixture that also contains, for example, carbon dioxide and carbon monoxide. We’re looking at these two steps in a holistic way to solve both challenges at the same time. This is where plasmas can help.
“When bulletlike electrons collide with a carbon dioxide molecule, they can directly decompose it or transfer energy to make it vibrate,” Guerra said. “This energy can be channeled, to a large extent, into carbon dioxide decomposition. Together with our colleagues in France and the Netherlands, we experimentally demonstrated the validity of these theories. Moreover, the heat generated in the plasma is also beneficial for the separation of oxygen.
