Abstract
Precisely controlling the two-dimensional (2-D) modular assembly of monolayer micelle building blocks into free-standing highly-ordered mesoporous crystalline nanomeshes with adjustable pore periodicity and configuration remains a significant challenge. Here, highly-uniform free-standing ultrathin mesoporous TiO<sub>2</sub> nanomeshes with periodically arranged pore arrays have been synthesized via a self-limiting modular monolayer assembly of monomicelles. The resultant free-standing mesoporous TiO<sub>2</sub> nanomeshes are perforated by monolayer long-range ordered hexagonal pore arrays with through mesopores ( ~25 nm in diameter), forming highly periodic 2-D mesostructures with a thickness of ~17 nm and a specific surface area of ~97 m<sup>2</sup> g<sup>-1</sup>. The pore periodicity can accurately be controlled from ~30 to 51 nm by varying the precursor-to-template ratio. As a proof of concept, the TiO<sub>2</sub> nanomeshes are deployed as anode protectors in Sn aqueous batteries, with a prolonged cycle life of over 1400 h at 1.0 mA cm<sup>-2</sup>.
