Abstract	We report amorphous MoSxCly as a high-performance electrocatalyst for both electrochemical and photoelectrochemical hydrogen generation. This novel ternary electrocatalyst is synthesized via chemical vapour deposition at temperatures lower than those typically used to grow crystalline MoS2 nanostructures and structurally characterized. The MoSxCly electrocatalysts exhibit stable and high catalytic activity toward the hydrogen evolution reaction, as evidenced by large cathodic current densities at low overpotentials and low Tafel slopes (ca. 50 mV decade−1). The electrocatalytic performance can be further enhanced through depositing MoSxCly on conducting vertical graphenes. Furthermore, MoSxCly can be directly deposited on p-type silicon photocathodes to enable efficient photoelectrochemical hydrogen evolution.
