水热法制备微晶氧化亚铜

Preparation of Microcrystal Cu_2O under Hydrothermal Condition

以CuSO4.5H2O和NaOH为原料,山梨醇、木糖醇为还原剂,采用水热法制备了相同条件下不同还原剂的微晶Cu2O.用X射线衍射(XRD)和扫描电镜(SEM)对其进行了表征.结果表明,当n(OH-)∶n(Cu2+)∶n(还原剂)=4∶1∶1,水热温度为180℃,反应时间为20 h时,生成产物全部为Cu2O,其形貌为八面体状.

The microcrystal Cu2O was prepared under same hydrothermal conditions with different reductant. CuSO4·5H2O and NaOH as main sources, D-sorbitol and xylitol as reductant. The product was characterized by XRD and SEM technology. The results show that when the ratio n（OH ） ： n（Cu^2＋ ） ： n（reductant） =4 ： 1 ： 1, at hydrothermal temperature of 180℃ after 20 h, all the product was microcrystal Cu2O by XRD and the morphology was octahedral by SEM.
