Among 2D layered chalcogenides materials, platinum tellurides can form various stoichiometries with a layered structure that has attracted significant attention due to their yield of low overpotentials for hydrogen evolution reaction. In this work, layered Pt₃Te₄ and PtTe₂ were synthesized and characterized, including their fundamental structural and electrochemical properties. We present a direct synthesis of Pt₃Te₄ and PtTe₂ from the respective elements, resulting in a monoclinic and trigonal crystal structure, respectively. Their electrocatalytic properties were tested and compared with each other for the hydrogen evolution and oxygen reduction reactions, showing promising results for future catalytic applications.
