Overview

Randomized trial explores electrocatalytic properties of cerium and lanthanum composites, suggesting improved performance.

Key Points

  • The aim is to develop Sr-free LaFeO3/CeO2-based composites that enhance conductivity and electrochemical performance through defect engineering.
  • Synthesized perovskite-fluorite composites using a one-pot route.
  • Characterized structural and microstructural properties through spectroscopy and lattice analysis.
  • Measured electrical conductivity and electrochemical properties in relation to cerium content.
  • Achieved optimal electrochemical performance with a cerium content of 0.16, improving activation energy and polarization resistance.
  • Indicated that Ce affects crystallization and defect chemistry, enhancing oxygen mobility.
  • Showed favorable interactions between perovskite and ceria phases, vital for functional properties.
