摘要:
分别采用直接沉淀法和快速沉淀法成功地制备了易于微孔道填充的纳米CuO粉末。直接沉淀法的铜源是无水CuSO4，沉淀剂是Na2CO3；快速沉淀法的铜源是Cu(CH3COO)2?H2O，沉淀剂是NaOH。通过XRD、SEM、TEM和SAED等分析手段表征产物的晶体结构、微观形貌及晶粒尺寸。结果表明，直接沉淀法的陈化时间对制备样品形貌和结构有影响。当前躯体陈化时间为3 h时，直接沉淀法制备的CuO纳米颗粒平均粒径约为25 nm；快速沉淀法制备的CuO纳米颗粒平均粒径约为6 nm。 与直接沉淀法相比，快速沉淀法制备的纳米CuO粒径更小、颗粒分散更均匀。
Abstract:
CuO nanoparticles easily filled in microchannels were successfully prepared by means of direct precipitation with copper sulfate as the starting material and sodium carbonate as the precipitant, and quick precipitation with copper acetate as the starting material and sodium hydroxide as the precipitant, respectively. The crystal structure, micro morphology and particle size of the samples were characterized by XRD, SEM, TEM and SAED. Results show that the micro morphology and the particle size of the samples prepared by direct precipitation are affected by the aging time. The average diameter of CuO nanoparticles synthesized by direct precipitation with the aging time of three hours was about 25 nm, and that synthesized by quick precipitation was about 6 nm. Compared with direct precipitation, finer and better-distributed CuO nanoparticles could be prepared by quick precipitation.
