在室温条件下,以锌粉1g、四氯化碳10mL和纯净水2 mL为比例,使用超声法制备出了Zn5(OH)8Cl2·H2O纳米片。探究了超声环境下Zn5(OH)8Cl2·H2O的生长机理,并对产物的形貌和结构进行了表征。研究了温度对Zn5(OH)8Cl2·H2O转化为ZnO的影响,发现产物在600℃下完全转化为六方结构纤锌矿ZnO,且高温有助于规则ZnO六方棱柱晶体的形成。使用Zn5(OH)8Cl2·H2O对初始浓度为20mg/L的甲基橙溶液进行光催化降解,结果表明,在15min时降解效率达到98.63%,30 min完全降解。
At room temperature, Zn5 (OH) 8Cl2 · H2O nanosheets were prepared by ultrasonic method using 1g of zinc powder, 10mL of carbon tetrachloride and 2mL of pure water. The growth mechanism of Zn5 (OH) 8Cl2 · H2O under ultrasonic environment was explored, and the morphology and structure of the product were characterized. The effect of temperature on the conversion of Zn5 (OH) 8Cl2 · H2O to ZnO was investigated. It was found that the product completely transformed into hexagonal wurtzite ZnO at 600 ℃ and high temperature contributed to the formation of regular hexagonal hexagonal prism crystals. The photocatalytic degradation of methyl orange solution with initial concentration of 20 mg / L using Zn5 (OH) 8Cl2 · H2O showed that the degradation efficiency reached 98.63% at 15 min and completely degraded at 30 min.
