* Carbon nanotube is microscopic molecule with a diameter of 1 nonometer (1 nanometer is one billion of a meter) that forms a long barrel of carbon connected by hexagonal rings. It is named after carbon planes that have been combined with three carbon atoms and have a honeycomb structure are made of a tube and shaped like a tube. Carbon nanotube, which is cylindrical carbon crystal with a diameter of 0.5 to 10 nm, is attracting attention as the next-generation advanced material because of its high tensile strength and electrical conductivity. Strength is 100 times better than steel, electrical conductivity is similar to copper, and thermal conductivity is the same as diamond. It is a futuristic new material that is light and flexible because it is hollow. Carbon nanotube is becoming a conductor and semiconducting material depending on the diameter of the tube. Utilizing these excellent properties, it is widely used as a versatile material for various fields such as semiconductors, flat panel displays, fuel cells, super-strong fibers, and biosensors. CNT electrode catalysts produced by HICNT have 1/3 metal characteristics, 2/3 have semiconductor characteristics, and the current density is 1000 times higher than that of copper. Electrolysis is possible even in the state of solution.

* An atom or molecule tends to become an ion, and it is easy to ionize because it tends to ionize and is easily oxidized. If you look at the ionization tendencies of metals, metals that are well oxidized will lose electrons. Also, the fact that it is easy to oxidize means that it is difficult to reduce it.

In electrolysis, the medium (electrode) used as the (+) and (-) electrode is not directly reacted, but is performed in the process of losing (oxidizing) the electrons in the electrolyte solution (reduction). When electricity is applied, the medium is oxidized while releasing the electrons from the (+) electrode medium which holds the electrons. At this time, the released electrons move to the (-) electrode medium and the (-) electrode medium causes the reduction. Electrolysis is not a uniform electrolytic reaction as a whole, but a non-uniform chemical reaction that is transmitted only around the electrode.
