Unraveling boron oxidation and structure in 2D Mo4/3B2−xTzvia solid-state NMR

Abstract

Atoms from i-MAB phases are selectively etched for boridene synthesis. However, water exposure severely hinders 2D boridene formation. By using NMR techniques, we precisely uncover the oxidation mechanism of boron and gain in-depth insights into the atomic-scale properties. Our findings offer a new avenue for advancing 2D boridene research.
