Summary

We synthesized isostructural metal-organic frameworks (MOFs) and found that enhancing proton conductivity improves electrocatalytic oxygen evolution reactions (OER). Higher conductivity in FJU-82-Co MOF led to significantly better OER performance compared to FJU-82-Zn.

Area of Science:

  • Materials Science
  • Electrochemistry
  • Catalysis

Background:

  • Metal-organic frameworks (MOFs) are promising materials for catalysis.
  • Electrocatalytic oxygen evolution reaction (OER) is crucial for energy conversion technologies.
  • Tuning material properties can enhance catalytic performance.

Purpose of the Study:

  • To synthesize new isostructural MOFs (FJU-82-Co/FJU-82-Zn).
  • To investigate the relationship between proton conductivity and OER performance in crystalline MOFs.
  • To demonstrate a strategy for improving electrocatalytic OER using MOFs.

Main Methods:

  • Synthesis of isostructural MOFs: FJU-82-Co and FJU-82-Zn.
  • Measurement of proton conductivity under specific temperature and humidity conditions.
  • Electrocatalytic OER performance evaluation, including overpotential measurements.

Main Results:

  • FJU-82-Co exhibited a proton conductivity of 7.40 × 10-5 S cm-1, 127-fold higher than FJU-82-Zn (5.80 × 10-7 S cm-1) at 60 °C and 98% RH.
  • FJU-82-Co showed a lower OER overpotential (0.57 V at 1 mA cm-2) compared to FJU-82-Zn (1.17 V).
  • A direct correlation between enhanced proton conductivity and improved OER performance was observed.

Conclusions:

  • Proton conductivity is a key factor for enhancing electrocatalytic OER in isostructural crystalline MOFs.
  • Tuning proton conductivity offers an effective strategy to improve MOF-based OER electrocatalysts.
  • The synthesized FJU-82-Co MOF demonstrates superior OER performance due to its higher proton conductivity.
