Design of Superhalogens Using Core-Shells Structure Model

Abstract

Superhalogen, having the electron affinity larger than that of any halogen, plays an important role in physical chemistry and materials design owing to its applications in hydrogen storage and lithium ion batteries. Inspired by the unique geometries and electronic properties of the II-VI/III-V cage clusters and especially the experimentally synthesized B12N12, herein we propose a core-shells structure model to design new superhalogens. The idea is assessed by ab initio calculations on the endohedral cage clusters X@B12N12 (X = F, Cl, Br) and many other similar systems. With an exceptionally large electron affinity of 5.36 eV, the stable F@B12N12 cluster behaves as a novel superhalogen that can serve as the building block of Li-salt and hyperhalogen. Our findings highlight a new route for the discovery of superhalogens, providing useful building blocks for the bottom-up design of materials.
