Semi-Conductive CNT Catalyst Electrode

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

Semi-Conductive CNT 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.

→ Development of an electrically conductive CNT composite material with excellent properties such as excellent dispersibility, low electrical resistance (surface resistance: less than 1Ω/cm2), and durability even with a high content of CNT
