Affordable and scalable process of a carbon nanotube-based catalyst outperforming platinum for electric-automobiles
Korean researchers from Ulsan National Institute of Science and Technology (UNIST), S. Korea, developed a novel bio-inspired composite electrocatalyst outperforming platinum.
This research work was published on June 25, in the journal Nature Communications.Â
The research team from UNIST, S. Korea, developed an inexpensive and scalable bio-inspired composite electrocatalyst, iron phthalocyanine with an axial ligand anchored on single-walled carbon nanotubes, demonstrating a higher electrocatalytic activity for oxygen reduction than the state-of-the-art Pt/C catalysts as well as an exceptional durability during cycling in an alkaline media.
Electrocatalysts for oxygen reduction are critical components that may dramatically enhance the performance of fuel cells and metal-air batteries, which are perceived to be the power for future electric vehicles.
Currently Pt and its alloy are known as the most efficient catalysts for activation of the oxygen reduction reaction. However, the application of them is limited due to their high costs and scarce reserves.
Scientists worldwide are speculating to find better catalysts which outperform platinum catalysts with low cost and simple production processes.
The UNIST research team led by Prof. Jaephil Cho, dean of the Interdisciplinary School of Green Energy of UNIST, demonstrated a new strategy to rationally design inexpensive and durable electrochemical oxygen reduction catalysts for metal-air batteries and fuel cells.
