纺锤状CuO纳米晶制备及催化性能的研究

Synthesis and Catalytic Property of Spindle-like CuO Nanocrystals

采用水热法,以醋酸铜为铜源,氢氧化钠为沉淀剂,聚丙烯酸为软模板,通过调控不同的合成参数,制备了纺锤状CuO纳米晶。同时重点探讨了聚合物种类和碱的浓度对CuO纳米晶产物形貌的影响。采用HRTEM、SEM、XRD、EDS、Raman等对产物的形貌、结构、成分、光学性质进行了表征。结果表明产物是纯的单斜CuO纳米单晶。并考察了纺锤状CuO纳米晶对甲基橙在H2O2协同作用下超声催化降解作用。

Spindle-like CuO nanocrystals were prepared with Cu（ac）2 as copper source,NaOH as precipitator and polypropylene as a soft template under controlling different synthesis parameters by a hydrothermal method.The effect of the kind of polymer and alkaline concentration on the morphologies of products were concentrated on discussing.The morphology,structure,component and optical property of CuO nanocrystals obtained were characterized by HRTEM,SEM,XRD,EDS,Raman respectively.The results showed that products were pure monoclinic CuO nanocrystals.At the same time,the catalysis degeneration of methyl orange solution under spindle-shaped CuO nanocrystalline in H2O2 synergistic effects by ultrasonic were also visited.
