Scalable, Bottom‐Up Synthesis of Transition Metal–Doped Quantum Confined, 1D Titanate‐Based Lepidocrocite Nanofilaments, Their Electronic Structures and Oxygen Evolution Reactivity

open access: yesAdvanced Materials Interfaces, Volume 13, Issue 3, 3 February 2026.
Quantum‐confined lepidocrocite titanate nanofilaments are doped, bottom‐up, with Mn+2, Fe+2, Co+2, Ni+2, and Cu+2 to tune electronic structure and catalysis. Doping narrows the bandgap—by up to ∼0.8 eV—and extends visible absorption. Ni‐doped filaments accelerate oxygen evolution (319 mV at 10 mA cm−2) and TM‐doped samples rapidly degrade rhodamine 6G (
