Abstract Plate-shaped Pb(Zr,Ti)O3 nanoparticles (PZT nanoplates) were synthesized by a hydrothermal method with oleic acid as a capping agent. With oleic acid, plate-shaped PZT nanoplates were obtained, whereas without oleic acid, large-sized PZT particles with rough surfaces were obtained. The sides of some PZT nanoplates synthesized with oleic acid had a unique step structure. The PZT nanoplates were characterized by various techniques. Fourier transform infrared spectroscopy revealed that the carboxylate group of oleic acid is chemically bound to the surface of PZT nanoplates. Selected area electron diffraction patterns revealed that these PZT nanoplates are single crystals and their normal axis corresponds to c-axis. These findings indicated that oleic acid played an important role in the formation of the uniquely shaped PZT particles.

油酸对锆钛酸铅纳米片形成的影响

摘要 以油酸为封端剂，采用水热法合成了片状Pb(Zr,Ti)O3纳米颗粒(PZT纳米片)。使用油酸，获得了板状的 PZT 纳米片，而没有油酸，获得了具有粗糙表面的大尺寸 PZT 颗粒。一些用油酸合成的 PZT 纳米片的侧面具有独特的阶梯结构。PZT 纳米板通过各种技术进行表征。傅里叶变换红外光谱表明油酸的羧酸根化学键合到 PZT 纳米片的表面。选区电子衍射图显示这些 PZT 纳米片是单晶，它们的法向轴对应于 c 轴。这些发现表明油酸在形成独特形状的 PZT 颗粒中发挥了重要作用。
