Making Oxygen from CO2  - interesting science news

Exploring space with all its complexities has one big issue; we as humans need oxygen and hence we need to carry our own oxygen wherever we go into space.

Scientists have now demonstrated a new chemical reaction for generating oxygen which could not only help us explore the universe but also fight climate change on Earth. They found that CO2 on collision with the comet surface effectively splitting it such that O2 gets released from the same CO2 molecule.

The researchers used a gold foil to mimic the comet surface in their experiments. The basic requirements are that the surface and CO2 should crash each other at a very high speed like in a comet. While the current efficacy is very low (2 O2 molecules from 100 CO2 molecules), further refinement is being done right now.
