Overview

Mixed-metal oxides enhance catalytic performance for water splitting, suggesting a new direction for sustainable energy.

Key Points

  • This research aims to evaluate how the composition and structure of mixed-metal spinels influence their performance as electrocatalysts for water splitting.
  • Synthesis of CuMn2O4 and Cu1.5Mn1.5O4 via hydrothermal route
  • Structural and microscopic analyses to assess morphology and composition
  • Electrocatalytic performance tested for hydrogen and oxygen evolution reactions
  • CuMn2O4 exhibits a hierarchical spear-like architecture enhancing catalytic efficiency
  • OER overpotential is only 290 mV, and HER overpotential is 17 mV at 10 mA·cm−2
  • Tafel slopes are 98.2 mV·dec−1 for OER and 59.1 mV·dec−1 for HER
  • CuMn2O4 shows excellent durability over 10 hours for OER and 16 hours for HER
  • Large electrochemically active surface area of 27.31 mF·cm−2 promotes charge transfer and mass transport
