Guided Heterostructure Growth of CoFe LDH on Ti3C2Tx MXene for Durably High Oxygen Evolution Activity (Small 3/2025)
Graphical Abstract
Oxygen Evolution
In article number 2404927, Hannu-Pekka Komsa, Bo Peng, Zhong-Peng Lv, and co-workers unveiled the guided growth of Co/Fe layered double hydroxide nanosheets (LDH) via the terminations on Ti3C2Tx MXene surface. The MXene surface chemistry regulates the structure and electronic properties in LDH-MXene heterostructures. A remarkably robust oxygen evolution reaction performance is demonstrated, where the overpotential only decays by 0.1% over 200 h operation.
