Ni3+doped monolayer layered double hydroxide nanosheets as efficient electrodes for supercapacitors

Abstract

Ni³⁺doped NiTi-LDH monolayer nanosheets with lateral dimensions ∼20 nm and a ultrathin thickness of ∼0.9 nm prepared through a facile bottom-up approach exhibit excellent supercapacitive performances, including extremely high specific capacitance (2310 F g⁻¹at 1.5 A g⁻¹) and long-term cycling life compared with bulk LDH.
