Black phosphorus/precious metal composite material as well as preparation method and application thereof

Abstract

The invention discloses a black phosphorus / precious metal composite material as well as a preparation method and an application thereof. The black phosphorus / precious metal composite material is a product prepared from precious metal nano-particles and / or precious metal alloy nano-particles through coordinate bond with black phosphorus, black phosphorus is modified with precious metal, so that black phosphorus cannot be oxidized in water and air, and stability of structure and performance of the black phosphorus material is enhanced; compared with the black phosphorus material and the precious metal / precious metal alloy nano-particles, the black phosphorus / precious metal composite material has excellent physicochemical characteristics, and catalytic performance of the black phosphorus / precious metal composite material is better than that of black phosphorus, therefore, the black phosphorus / precious metal composite material can be applied to a wider catalysis field and can be taken as an efficient photocatalyst, an electrocatalyst and an organic catalyst to be applied to the fields of photocatalysis, electrochemistry, organic catalytic reaction and the like.

Description

technical field

[0001] The invention relates to the technical field of black phosphorus materials, in particular to a black phosphorus / noble metal composite material, its preparation method and application. Background technique

[0002] Two-dimensional black phosphorus (referred to as black phosphorus) is a new type of two-dimensional semiconductor material that has attracted extensive attention. As a member of two-dimensional planar materials, black phosphorus has a two-dimensional layered structure similar to graphene. The phosphorus atoms in the same layer are connected by covalent bonds, and the layers are stacked together by van der Waals force. Through nearly three years of research, black phosphorus has shown many unique properties. First of all, compared with the zero band gap of graphene and the indirect band gap (above the second layer) of transition metal sulfides, black phosphorus is a direct band gap semiconductor, that is, the bottom of the conduction band and...
