Overview

Demonstrates high hydrogen selectivity and permeability in a graphene-based membrane, suggesting its potential in clean-energy systems.

Key Points

  • The research aims to develop a graphene/phosphoric acid membrane for efficient hydrogen purification from carbon dioxide.
  • Fabrication of a graphene/phosphoric acid mixed proton-electron conducting membrane.
  • Assessment of hydrogen selectivity and permeance at elevated temperatures in a membrane reactor setup.
  • Evaluation of thermal stability and conduction properties of the membrane.
  • Achieved nearly 100% selectivity for hydrogen over carbon dioxide.
  • Reached a hydrogen permeance of 69 GPU at 250°C.
  • Demonstrated significant improvements in proton and electron conduction due to membrane design.
