Design, synthesis and electrocatalytic properties of coaxial and layer-tunable MoS₂nanofragments/TiO₂nanorod arrays

Abstract

We manipulate layer-controllable XL-MoS₂ (X = 1, 2, 3, F, where F = 4-6 layers) along the axial direction of vertically aligned TiO₂ nanorod arrays on conducting substrates to form a coaxial, ordered and quasi-one-dimensional structure, introducing an electron transport highway and electrolyte diffusion channels to improve electrocatalysis from triiodide to iodide.
