Synergistic Integration of SrFeO3 Nanoparticles With Exfoliated MXene (Ti3C2Tx/V2CTx) Nanosheets for High Performance Supercapacitors

Small, EarlyView.
A facile mechanical mixing, probe‐sonication, and annealing strategy was employed to intercalate SrFeO3 nanoparticles between Ti3C2Tx and V2CTx MXene sheets, constructing robust heterostructures for advanced supercapacitors. The inserted perovskite suppresses MXene restacking while contributing additional Faradaic redox activity.
