Is It Possible To Decompose CO2 Into C And O2? Here's The Explanation

As you can see, you can use photosynthesis of plants. Plants use solar energy to break down CO2 into C and O2.

I think there is no other way to decompose CO2 than photosynthesis (I don't know). But energy is needed. It is absolutely necessary as a providence of this world. The combination of C and O2 is called oxidation, and it means "burning", so you can see that heat energy is extracted. Decomposition is called reduction in the reverse process, and energy must be input to it. What if you got that energy from thermal power? It will be said that.

By the way, "I need energy to do it"-remember that it will be an exam in various places, so you will be on the exam. There are many people who do not understand and are danced.

For example, an electric scooter that runs on water. Are you stupid, "Wow!" Water is not a source of energy because it is a chemically stable molecule, that is, it has a low chemical potential. The energy source is (usually) the high chemical potential of magnesium metal in magnesium batteries.

Magnesium is an almost inexhaustible element in seawater, so some people think that this solves the energy problem! Magnesium in seawater is produced as a compound with low chemical potential, such as magnesium chloride, so it is not that the seawater is full of energy. Energy is required to refine the magnesium compound into metallic magnesium, which means that the electric power obtained from thermal power generation is usually used, and the electric scooter is moved by the energy input there.

Therefore, the magnesium metal in the magnesium battery that has generated electricity has been changed to magnesium hydroxide with a low chemical potential. In order to reduce this to metallic magnesium again, energy is needed, and if it is obtained from thermal power generation, what are you doing from the perspective of solving energy problems and global warming problems! It will be said that.

If magnesium hydroxide is heated to a high temperature in a solar furnace, it can be reduced to metallic magnesium, and those who are studying it are those who are seriously studying the use of natural energy. The person who is listening to "it is an electric scooter that moves when water is supplied" is a scammer.
