2d anisotropic bismuth materials and method for obtaining same using colloidal synthesis

Abstract

A 2D bismuth material, also called bismuthene, has a sandwich-like sheet structure with at least two outer layers formed by organic molecules containing sulphur atoms that form Bi—S bonds and at least one inner layer formed by a crystalline network of Bi(0) atoms. These materials are useful in electronic, optoelectronic, catalytic applications or in energy storage and transformation. Furthermore, a process produces this material from a bismuth salt that reacts with an amine and subsequently with a thiol by effect of the application of radiation and a subsequent reduction. This process has a colloidal approach to producing Bi(0) crystals based on a photocatalytic reduction of a soluble Bi(III) organometallic complex leading to the generation of the crystals.
