In this article, the MOF-199 are synthesized by hydrothermal and electrochemical synthesis methods and the effect of synthesis producers are investigated on its catalytic performance for HER electrocatalysis. The Cu-Pd/nanoporous carbon composite-electrochemical (Cu-Pd/NPCCelectro) and Pd/nanoporous carbon composite-hydrothermal (Cu-Pd/NPCC-hydro) were synthesized by utilization of Cu/NPCC-electro and Cu/NPCC-hydro as a precursor for galvanic replacement reaction (GRR) of its Cu atoms by Pd (IV) ions, upon immersion in a palladium chloride solution. The synthesized materials was characterized by XRD, SEM, FT-IR, and BET technique.
