The "edge-free" monolayer MoS2 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 MoS2 and the formation of catalytically active sites for HER.
无边缘的单层 MoS2 薄膜负载在 3D 纳米多孔金上，对氢的析出反应（HER）具有高催化活性，这源于大的面外应变，这种应变在几何上需要管理双连续纳米多孔结构的 3D 曲率。大的晶格弯曲导致 2H MoS2 的局部半导体到金属的转变，以及形成 HER 的催化活性位点。
