Interface Engineering of CoS2/Co(OH)F Heterostructures for In Situ Co4+ Formation and Enhanced Oxygen Evolution Reaction.
The directional reconstruction into high-valent active species is critical for enhancing the oxygen evolution reaction (OER) kinetics and, consequently, the overall efficiency of water electrolysis for green hydrogen production. Here, we introduce the interfacial engineering of Co(OH)F nanosheets anchoring with CoS2 pa...
