Development of an electrochemical advanced manufacturing technique for the production of low-cost carbon nanotubes from carbon dioxide
Carbon nanotubes have long been touted as the supermaterial that would change the world, with applications ranging from energy, electronics, automotive, aerospace, and medical. However, they have thus far achieved limited commercial success due to their high price, which is a result of the energy intensive limited-scale manufacturing methods currently deployed, which often have environmentally harmful by-products.
SkyNano has developed an electrochemical manufacturing technology to produce carbon nanotubes in a scalable ambient pressure system, and uses only inputs of CO2 and electricity, resulting in low operating expenses and no toxic by-products. This technology will enable new products and applications due to the low-cost and scalable nature of the technology.
Many technological innovations such as better batteries, stronger and lighter-weight materials for building, auto, and aero applications, and next-generation electronics rely on advanced materials such as carbon nanotubes which are currently too expensive for most applications.
The cost and practicality of carbon dioxide conversion relies on the ability to produce high value secondary products from carbon dioxide, which is enabled by conversion to technologically valuable materials such as carbon nanotubes.
Other carbon nanotube manufacturers
SkyNano advantage: low capital expenses, low operating expenses, no toxic by-products, simple feedstock and inputs: electricity and CO2
Other advanced materials such as graphene
SkyNano advantage: Carbon naontubes have been researched for the past 2 decades, and despite their high cost bottlenecking commercial success, the materials have already been developed into many applications by both commercial and academic sectors. SkyNano’s technology will allow these applications to reach the market through economic feasibility enabled by our low cost manufacturing technology.

Proof of concept demonstration for growth of multi-walled carbon nanotubes at Vanderbilt University and basic understanding of how catalysts influence resulting carbon nanotube structures. The next step is to apply this understanding to make controlled small diameter catalysts for single-walled carbon nanotube growth.
