Holmium-induced lattice engineering of SmFeO3 perovskite nanoparticles for high-performance symmetric supercapacitors in redox-active KI/KOH electrolyte
This study presents Ho-doped SmFeO3 nanoparticles synthesized via citrate combustion to enhance supercapacitor performance through lattice engineering. Characterization confirmed that Ho3+ substitution induces compressive microstrain and a refined nanoscale structure. Electrochemical evaluations in a symmetric two-elec...
