Alternating Misfit Layered Transition/Alkaline Earth Metal Chalcogenide Ca3Co4O9 as a New Class of Chalcogenide Materials for Hydrogen Evolution.

摘要: Layered misfit chalcogenide structures have garnered much attention and prestige in several applications such as thermoelectric materials and high-temperature superconductors. However, its potentials for important electrochemical applications such as hydrogen evolution and oxygen reduction reactions have not been systematically studied. Till date, such applications have mainly applied precious metal and oxides with perovskite-or spinel-based structures. In this work, we synthesized a misfit layered mixed oxide in the …
