Overview of Catalyst Electrode
▪ Increasing need for Using water electrolysis in various industrial application
▪ Catalyst, a Key element of electrode, made with precious metals (platinum, ruthenium oxide, rubidium oxide) limit the industry growth
▪ Studies are going on for the catalyst electrode process technology and design with the nano polymerization, non-metallic/no-metal materials
▪ Problem of electrolysis by Metal catalyst electrode: Instability (solvation of metal materials, catalytic activity, redox activity ↓), low durability, reduction of electrode life
What is CNT?
▪ "CNT” consists of molecules of 1 nanometer diameter (1 billionth meter), made of carbon atoms linked in hexagonal rings forming a long tubular shape
▪ It is a future-oriented new material with lightweight, flexibility, and absorbency
▪ Tube diameter determines metal and semiconductor properties.
Overview of Catalyst Electrode
• When compounding with existing polymer materials, the specific surface area of carbon nanotubes (hereinafter CNT) is large and the apparent density is 0.02~0.05 g/cc, so it is difficult to increase the CNT content above a certain amount
• If the content of CNT is increased, the durability is weakened (easy to break) and the dispersibility is lowered.
When compounded with existing polymer components, the large specific surface area of CNT and apparent density of 0.02 - 0.05g/cc make it difficult to increase CNT content beyond a certain amount. Increasing CNT content weakens durability and makes products more fragile and reduces dispersion.
⇛ EcolGreenTec Co., Ltd. has developed and applied for patents on electrically conductive CNT composite materials with high CNT content, excellent dispersion, low basal resistance (surface resistance: 1/- or less), and superior durability.
