The development of highly active and durable electrocatalysts for oxygen evolution reaction (OER) or Hydrogen evolution reaction (HER) in acidic media is an important issue for high performance electrochemical conversion and storage applications such as fuel cells and metal-air batteries. A transition metal or metal oxide doped Ruthenium was recently shown to greatly boost the activity and durability of Ru based electrocatalysts for the OER or HER. Molybdenum phosphide exhibits high activity towards the HER in both acid and alkaline media even in bulk form. UiO-67 is a Zr-based MOF which can provide the oxygen-vacancy required for the reverse water gas shift reaction and can be used as a support for highly dispersed nanostructured catalysts to prevent nanoparticles from sintering and aggregation at high temperature, maintaining its catalytic activity. In this study, we synthesized Mo doped UiO-67 using microwave-assisted synthesis method as efficient and stable electrocatalyst support, followed by Ru impregnation for HER or OER. The synthesized catalysts were analyzed by BET, XRD, FE-SEM and electrochemical experiment. |
