GQD combined with graphene create an excellent fuel-cell catalyst
In 2013, Rice University researchers developed a simple method to reduce coal into graphene quantum dots (GQDs). Now the researchers combined these GQDs with small graphene oxide (GO) sheets to create an excellent catalyst for fuel-cells.
To create the new materials, the researchers boiled a solution of GQDs and GO sheets - which combined them into self-assembling platelets. Treating those platelets with nitrogen and boron created a material with an abundance of edges for chemical reactions (for oxygen reduction), and excellent conductivity.
