摘　　要：为探寻纳米材料的绿色合成方法,以性质温和、无毒的食品级蔗糖酯作为表面活性剂,用六水合硝酸锌和氢氧化钠为主要原料通过搅拌超声沉淀法制备纳米氧化锌,并采用X射线衍射分析、紫外光谱分析及透射电镜分析对产物进行表征,进一步确定了所合成产物的结构、物相、大小及形貌。结果表明,氧化锌达到纳米级别,尺寸为40 nm左右,而蔗糖酯能够有效改善纳米粒子的团聚现象。Aim to find an environmentally friendly method for synthesis of nano meter materials. Nano zinc oxide was synthesized by precipitation of sodium hydroxide and zinc nitrate hexahydrate with mild, non-toxic food grade sucrose esters as surfactant with stirring and ultrasound. The as-synthesized nanoparticles were characterized by XRD, UV-VIS and TEM. The size of Zn O particles was about 40 nm. It was proved that sucrose ester could reduce the reunion of nanoparticles.
