Abstract

Uniform transition metal sulfide deposition on a smooth Tio? surface to form a coating structure is a well-known challenge, caused mainly due to their poor affinities. Herein, we report a facile strategy for fabricating mesoporous 3D few-layered (<4 layers) MoS2 coated Tio? nanosheet core-shell nanocomposites (denoted as 3D FL-MoS2@Tio?) by a novel two-step method using a smooth Tio? nanosheet as a template and glucose as a binder. The core-shell structure has been systematically examined and corroborated by transmission electron microscopy, scanning transmission electron microscopy, and X-ray photoelectron spectroscopy analyses. It is found that the resultant 3D FL-MoS2@Tio? as a lithi
