Probing metal/high-entropy perovskite heterointerfaces for efficient and sustainable CO2 electroreduction

A novel high-entropy Sr 2 Fe 0.4 V 0.4 Mo 0.4 Ni 0.4 Ti 0.6 O 6− δ (SFVMNT) perovskite, coated with in situ exsolved NiFe alloy nanoparticles, is proposed as a promising cathode material for solid electrolysis cells for CO 2 electrolysis.
