Fluorine-doped BP 2000: highly efficient metal-free electrocatalysts for acidic oxygen reduction reaction with superlow H2O2 yield.

Fluorine-doped carbon blacks as inexpensive, high performance electrocatalysts for acidic oxygen reduction reaction were synthesized. The performance of the optimal catalyst (BP-18F) is close to the level of other reported best non-Pt electrocatalysts in acid, but with superlow H2O2 yield (<0.1%) ever. Their high performance is confirmed by quantum calculations.
