Fluorine dopants in tungsten sulfide boost the efficiency of H 2 O 2 electro-synthesis via the oxygen reduction reaction.

In this work, we report fluorine-doped tungsten sulfide as an exceptional electrocatalyst for H 2 O 2 generation (95% at 0.6 V vs. RHE). The fluorine dopants boost the catalytic efficiency by reducing the binding strength between the catalytic center and OOH* species.
