Trifunctional Electrocatalysts: Graphene Composites with Cobalt Sulfide: Efficient Trifunctional Electrocatalysts for Oxygen Reversible Catalysis and Hydrogen Production in the Same Electrolyte (Small 33/2017)

In article 1701025, Ligui Li, Shaowei Chen, and co-workers, develop a series of nitrogen and sulfur-codoped graphene composites with a high content of cobalt sulfide nanoparticles, which can serve as low-cost and efficient trifunctional electrocatalyst towards oxygen reversible catalysis and hydrogen production in a full-water electrolyzer in the same alkaline electrolyte.
