How To Split Hydrogen And Oxygen
Hydrogen and oxygen evolution method of water
In the ancient times, those who want to understand the art of hydrogen and oxygen evolution must first study the nature of water. Water is a hydrogen-oxygen compound, and its molecular formula is H 2O O. If you want it, you need to understand the reason and seek the method.
First, the method of electrical analysis. Place an electrode in the water and pass an electric current. Electricians can also promote the decomposition of water. At the anode, oxygen ions lose electrons and become oxygen to escape; on the cathode side, hydrogen ions gain electrons and gather into hydrogen gas. This process requires appropriate voltage, current, and good conductivity electrodes, such as graphite, platinum, etc. And the electrolyte also pays attention to, soluble salts or acids and bases, such as sodium sulfate, sodium hydroxide, can increase the conductivity of water and promote the rapid reaction.
Second, the method of photolysis. Choose a suitable catalyst, such as titanium dioxide, etc., and place it in the place of water and light. Light can also stimulate the electrons of the catalyst, producing electron-hole pairs. Holes have strong oxidizing properties, which can capture electrons from water and cause water decomposition; electrons combine with hydrogen ions in water to generate hydrogen. This way requires a photosensitive catalyst, and the light intensity and spectrum are affected. If you want to achieve high efficiency, you must study it carefully.
There is also a method of pyrolysis. Raising the temperature of water to extremely high, the molecular movement of water is dramatic, and the bond energy is insufficient to maintain, and the hydrogen and oxygen are separated. However, it requires extremely high temperature, constant thousands of degrees, and huge energy consumption, so practical application is quite difficult, but theoretical exploration is not without value.
The art of hydrogen and oxygen evolution is related to a new way of energy. Hydrogen is also a clean energy, and the combustion products are only water, which is not polluted in the environment. If hydrogen and oxygen can be efficiently separated, the energy dilemma may be solvable, and the world environment will be better. Therefore, those who seek this art should study the principles of physics and chemistry, and make unremitting explorations, looking forward to the future, creating efficient methods, and benefiting all people.
