Abstract

The invention discloses a preparation method of a cuprous oxide nano material and hydrogen evolution performance of the cuprous oxide nano material, and belongs to the technical field of nanometer materials. According to the preparation method, ethylene glycol and diethylene glycol are used as reducing agents, copper hydroxide and basic copper carbonate with specific morphology are used as coppersources, and the copper hydroxide and the basic copper carbonate copper are reduced to form cuprous oxide nano material with maintained morphology under the protection of inert gas through a gas phasereduction method. The reaction steps are simple and are environmentally friendly, the obtained product does not need to be washed, and a pure cuprous oxide product can be obtained. According to the preparation method provided by the invention, the simple and rapid method is adopted for synthesizing the cuprous oxide nano material with the maintained morphology, and the prepared cuprous oxide nanomaterial has the performance of electro-catalytic hydrogen evolution.
