Multi-walled carbon nanotubes
We specialize in the conversion of plastic waste into multi-walled carbon nanotubes (CNTs). Plastic waste is first decomposed by heating into gas via pyrolysis. The gas is then utilized in our innovative catalytic system to grow CNTs via a chemical vapor deposition process. After the synthesis, CNTs are purified and functionalized using water-free techniques, allowing for efficient metal recovery and avoidance of hazardous liquid waste. Owing to our purification process, CNTs have low content of metal impurities.
