Problems solved by technology

[0003] Using a method similar to exfoliating graphene, the research group of Professor Pablo Ares successfully obtained nanometer-thick antimonene crystals by mechanical exfoliation. Experiments have proved that few-layer antimonene has good stability at room temperature, but the preparation method is inefficient. It is not conducive to the research and application of antimonene

Abstract

The invention discloses a method for preparing antimonene with a liquid phase method. The method is characterized by comprising the following steps: mixing lamellar beta-antimony with an aqueous solution of phytic acid; performing ultrasonic pyrolysis treatment and centrifuging treatment in sequence; dispersing a large amount of single-layer or less-layer antimonene in supernatant of a product. By adopting the method, the antimonene which has a single layer to the maximum extent can be produced on a large scale; the method is low in cost, is high in yield, and contributes to further scientific research, popularization and application of the antimonene.

Description

technical field [0001] The invention relates to the preparation of novel two-dimensional materials, in particular to a method for preparing antimonene by a liquid phase method. Background technique [0002] Since the discovery of graphene, two-dimensional materials have become a research hotspot in both basic and application aspects due to their unique dimensional characteristics. In recent years, research in this field has started from graphene, and gradually expanded to disulfides and the fourth group (silicon, germanium, tin), and then to the fifth group (phosphorus, arsenic, antimony, bismuth). Atomic-thick two-dimensional crystal materials, such as graphene, silicene, and germanene, etc., exhibit excellent properties and are widely used in information and energy devices. However, these carbon-family 2D crystals also expose a serious weakness, namely zero bandgap, which seriously affects their applications in electronic and optoelectronic devices. In addition, the band...
