Copolymer hybrid films consisting of polypyrrole/MoS x ( x ≈ 5) with significantly enhanced electrocatalytic activity for the hydrogen evolution reaction (HER) are fabricated by a one‐step electrochemical copolymerization of pyrrole and (NH 4 ) 2 MoS 4 . The films show a Tafel slope of 29 mV dec −1 and an onset potential of 0 V vs. RHE, which is comparable to those of commercial Pt/C catalysts.
