Graphite rods in the application of electrolytic water treatment

Electrolysis of water, the process of producing hydrogen and oxygen through the electrolysis of H2O using direct current, is known as water electrolysis. When an electric current passes through water (H2O), hydrogen (H2) is formed at the cathode through the reduction of water, and oxygen (O2) is formed at the graphite anode through the oxidation of water. The amount of hydrogen generated is approximately twice that of oxygen. Water electrolysis is the next-generation method for preparing hydrogen fuel, replacing steam reforming.

Conditions for forming an electrolytic cell: (1) Direct current power supply. (2) Two electrodes, where the electrode connected to the positive terminal of the power supply is called the graphite anode, and the electrode connected to the negative terminal is called the cathode. (3) Electrolytic solution or molten electrolyte. Water

In (H2O), ions are often in a state of disordered movement. When direct current is applied, the ions move in a directional manner. At the anode, oxidation reactions occur, while at the cathode, reduction reactions take place. Cations move towards the cathode, where they gain electrons and are reduced; anions move towards the anode, where they lose electrons and are oxidized. During the process of water electrolysis, OH- ions lose electrons at the graphite anode, becoming oxygen and being released as oxygen gas; H+ ions gain electrons at the cathode, becoming hydrogen and being released as hydrogen gas. The resulting oxygen and hydrogen gases.
