Low-Cost, Bi-Functional Carbon Nanotube Sponges

Yu_images_700x532A group from Texas A&M University, led by Dr. Choongho Yu, have developed a carbon nanotube sponge that could lower the cost in the effort to commercialize electrochemical cells.

The researchers’ aim was to develop a material to replace the expensive Pt-based catalyst currently used in many electrochemical systems. While other researchers have previously attempted the same feat, the results typically showed low stability levels.

This from Texas A&M University:

[The team has] developed a new low-cost and scalable method to synthesize 3-D sponge-like carbon nanotubes, which are self-standing and highly porous. After post-treatment, striking catalytic activity and stability are found to be comparable to or better than those of Pt-based catalysts in both acidic and basic environments.

The researchers believe that these results could allow the commercialization of current lab-based electrochemical cells due and potentially lower the price of commercial fuel cell stacks.
