One-Step Electrodeposition of Co9S8 on Ni Foam for Efficient Alkaline Overall Water Splitting
Developing binder-free, earth-abundant bifunctional electrocatalysts for alkaline overall water splitting is crucial for scaling alkaline water electrolysis beyond noble-metal electrodes. In this work, nonacobalt octasulfide (Co9S8) is directly grown on nickel foam through a binder-free, one-step galvanostatic electr...
