Abstract: Anion exchange membrane (AEM) water electrolysis is an emerging technology for potentially large-scale hydrogen generation owing to the low cost of catalysts based on transition metals. To date, it is still in the laboratory stage for single-cell tests due to the stability issues fromthe membrane, cathodic and anodic catalysts. Particularly, the anodic catalyst for oxygen evolution reactions (OER) is highly unstable under such strong polarization. Recently, transition metal sulfides (TMS) have been widely used as anodic catalysts for their promising activity and stability.However, research on TMS focuses on in-situ growth on nickel foams and the corresponding halfcell performance, which leads to uncontrollable mass loading, poor repeatability, and low practicality. Moreover, matrix-free synthesis of sulfides with three-dimensional (3D)nanostructures and their morphological and structural evolutions during OER processes are rarely reported.
