Electrochemical water splitting is a highly promising strategy to produce high purity hydrogen. To reduce costs, it is critical to develop non-precious-metal catalysts displaying high catalytic activity toward the hydrogen evolution reaction (HER). Here, we develop a flexible approach to synthesize hierarchically porous CoxFe1–xS2@carbon (x ≈ 0.36) superparticles with mesopores, macropores, and carbon shell structures. CoxFe1–xS2@carbon superparticles exhibited excellent HER activity and catalytic stability.
