Abstract

The invention relates to a preparation method for cuprous oxide micron / nano crystal with controllable morphology, relating to the preparation method for the cuprous oxide micron / nano crystal. The invention mainly solves the technical problems of high cost and environmental pollution in the preparation process of the micron / nano cuprous oxide. The method comprises the following steps of: 1, dissolving copper salt into ultrapure water, pouring lactic acid, continuously stirring, regulating a pH value, cooling to the temperature of 25 DEG C, keeping constant volume, measuring the pH value, and obtaining solution A; 2, moving the solution A to a hydrothermal reaction kettle, sealing the reaction kettle, putting the hydrothermal reaction kettle into a drying oven, keeping the temperature, naturally cooling to a room temperature, centrifugally washing by using the ultrapure water, centrifugally washing by using anhydrous ethanol, transferring the reaction kettle onto watch glass, and drying the reaction kettle in the drying oven; and thus obtaining the cuprous oxide micron / nano crystal. The preparation method for the cuprous oxide micron / nano crystal with the controllable morphology has the advantage of simpleness and practicability, simple equipment operation, low raw material price, easy synthesis, less pollution to environment and high synthetic concentration, the problem of the cost of the morphology control and industrialized large-scale synthesis in the prior art is solved, and the industrial production is facilitated.

Description

technical field

[0001] The invention relates to a method for preparing cuprous oxide micro / nano crystals; in particular, it relates to a preparation method for shape-controllable cuprous oxide micro / nano crystals. Background technique

[0002] Cuprous oxide is a semiconductor material with a p-type direct bandgap. The forbidden band width is 1.9-2.2ev. Cuprous oxide semiconductor material can be excited under visible light (wavelength 400-800nm), and can be used in solar energy conversion, micro Electronics, magnetic storage, catalysis and gas sensing and other fields.

[0003] The preparation of cuprous oxide nanomaterials has always been one of the hot research areas. Cuprous oxide thin film materials also have good applications in solar energy conversion. For example, Yan Zipeng and others prepared p-type Cu by electrochemical method 2 O semiconductor thin film (Journal of Xi'an Jiaotong University, 2011, 45(3): 121-124), and in the study of direct conversion of solar ...
