Efficient synthesis method of Prussian blue functionalized black phosphorus quantum dot hybrid material

Abstract

The invention relates to the field of nano material preparation, in particular to an efficient synthesis method of a Prussian blue functionalized black phosphorus quantum dot hybrid material, and the efficient synthesis method comprises the following steps: preparing a BP nano material through a liquid phase stripping method; then the prepared BP nano material reacts with a Prussian blue precursor in an organic system to prepare a hybrid nano structure with complementary performance, and the stability of the material is improved while the photoelectric performance of the material is maintained or even improved. The black phosphorus quantum dots are loaded on a Prussian blue porous net structure by utilizing the interaction force between rich lone electrons of the black phosphorus and cyano groups, so that the specific surface area and charge transfer channels of the material can be increased, the environmental stability of the black phosphorus can be enhanced, and the black phosphorus has higher catalytic activity and stability. The method is simple to operate and mild in reaction condition, and can realize large-range and high-efficiency preparation of the black phosphorus-based hybrid material.

Description

technical field [0001] The invention relates to the field of nanomaterial preparation, in particular to a high-efficiency synthesis method of a Prussian blue functionalized black phosphorus quantum dot hybrid material. Background technique [0002] As a rising star among two-dimensional materials, black phosphorus (BP) has been widely studied due to its excellent carrier mobility and tunable direct band gap. BP also has the advantages of high charge carrier mobility of graphene and adjustable direct bandgap of transition metal chalcogenides, making it an indispensable general-purpose two-dimensional material in the fields of electronics, optoelectronics, biomedical batteries, and catalysis. Because the BP nanostructure is particularly sensitive to humidity, the phosphorus atomic layer on its surface is easily transformed into a hybrid structure of phosphorus oxide and cannot exist stably. Therefore, it is of great significance to explore the synthesis method of efficient an...
