Abstract

The invention discloses a method for preparing ordered nano cuprous oxide polycrystalline powder. The method comprises the following steps of: (1) dissolving copper salt into water to obtain copper salt solution, preparing sodium dodecyl sulfate-reducing agent-alcohol solution, then mixing the two kinds of solution, and preserving heat of the mixed solution for later use; (2) dissolving precipitant into water to obtain precipitant solution, and then adding alcohol into the precipitant solution to form precipitant-alcohol-water mixed solution; (3) preheating and dissolving the mixed solution prepared in the step (2), quickly adding the mixed solution into a flask in the step (1), heating the mixed solution to a reflux temperature, and refluxing and reacting the mixed solution for 7 to 48 hours; and (4) standing the obtained product, and washing and drying the sediment to obtain the ordered nano cuprous oxide polycrystalline powder product. The obtained cuprous oxide powder is high ordered (namely space symmetry) nano laminar polycrystalline structural pure cuprous oxide, the adopted low-toxicity sodium dodecyl sulfate surfactant is favorable for non-toxic production and environmental protection, and the raw materials are common chemical reagents and are cheap and easily obtained.

Description

technical field [0001] The technical solution of the invention relates to low-valence oxides of copper, in particular to a method for preparing ordered nano-cuprous oxide polycrystalline powder. Background technique [0002] Cuprous oxide is an important inorganic oxide consisting of 88.1% copper atoms and 11.9% oxygen atoms. It is a low-valence oxide of copper, and its English name is Cuprous oxide or Copper(I)Oxide. Molecular formula is Cu 2 O, molecular weight 143.09, density 6.0g / cm 3 , with a melting point of 1235°C. Cuprous oxide is generally red or orange-yellow octahedral cubic crystalline powder. Due to different preparation methods and particle sizes, it can appear in various colors such as yellow, orange, red or purple. [0003] As a p-type semiconductor material with unique optical and magnetic properties, cuprous oxide has potential applications in solar energy conversion, electronics, magnetic storage devices, biosensing and catalysis. The bandgap width of...
