Atomically thin SiC nanoparticles obtained via ultrasonic treatment to realize enhanced catalytic activity for the oxygen reduction reaction in both alkaline and acidic media

Abstract

Atomically thin SiC derived from commercial SiC and possesses prominent ORR catalytic activity, comparable with Pt/C. The ORR process is dominated by a 4-electron pathway. Atomically thin SiC also exhibited outstanding durability and methanol crossover resistance.
