Abstract

The present invention discloses a layered porous cuprous oxide octahedron material preparation method, which comprises: adopting a copper salt, triethanolamine and glycerol as raw materials, adopting distilled water as a solvent, carrying out a hydrothermal reaction for 6-18 h at a temperature of 160-180 DEG C in a polytetrafluoroethylene autoclave to obtain brick-red precipitate, centrifugating, washing, and drying so as to prepare the layered porous cuprous oxide octahedron material. According to the present invention, the used raw materials such as the copper salt, the triethanolamine, the glycerol and the like have characteristics of low price and easy obtaining, and the surfactant or templating agent is not used, such that the cost is reduced, and the operation steps are simplified; and the prepared layered porous cuprous oxide octahedron material has the large surface area, and provides potential application values in the fields of photocatalytic degradation dyes, gas sensitivity, energy storage, lithium batteries, and the like.

Description

technical field [0001] The invention relates to a method for preparing cuprous oxide, in particular to a method for preparing a layered porous cuprous oxide octahedral material. Background technique [0002] As an important p-type semiconductor material, cuprous oxide has a band gap of 2.0-2.2ev, and is one of the few semiconductor materials that can be excited by visible light. It has broad application prospects in photocatalysis, solar cells, sensors, lithium-ion batteries, and magnetic storage. At the same time, cuprous oxide is also an important industrial raw material, which has extensive and important uses in shipbuilding, water treatment, electronics and other industries, as well as in agricultural production. Due to Cu 2 The morphology and structure of O greatly affect its physical and chemical properties. Therefore, the synthesis of micro-nano Cu with controllable morphology and structure 2 O has become a research focus and focus. At present, there have been man...
