Carbon nanotube–graphene complexes show promise as low-cast, high-activity electrocatalysts for fuel cells or metal-air batteries 28 May 2012 This drawing shows the damaged outer wall of a carbon nanotube with nanosized graphene pieces (white patches), which facilitate the formation of catalytic sites made of iron (yellow) and nitrogen (red) atoms. The catalyst reduces oxygen to water. Click to enlarge. A team of researchers has demonstrated the ability of “partially unzipped” carbon nanotubes to act as an oxygen reduction electrocatalyst in both acidic and alkaline solution. The work, led by Stanford University’s Dr. Hongjie Dai, and reported in the journal Nature Nanotechnology , could lead to lower-cost alternatives to platinum for use in fuel cells and metal-aire batteries. In the new process, the outer walls of the few-walled carbon nanotubes are partially unzipped, c...
