The “edge‐free” monolayer MoS 2 films supported by 3D nanoporous gold show high catalytic activities towards hydrogen evolution reaction (HER), originating from large out‐of‐plane strains that are geometrically required to manage the 3D curvature of bicontinuous nanoporosity. The large lattice bending leads to local semiconductor‐to‐metal transition of 2H MoS 2 and the formation of catalytically active sites for HER.
