Raise your cup! The template-free pyrolysis of natural seaweed results in “seaweed carbon” (SCup) with a high surface area and doped nitrogen and sulfur heteroatoms as a metal-free electrocatalyst for the oxygen reduction reaction. The reaction proceeds through a four-electron pathway in alkaline media, and the activity is comparable to that of the Pt/C catalyst, but SCup shows enhanced durability and methanol tolerance.
