Regular BiPO4 nanorods, for the first time, and BiOCl lamellae have been successfully synthesized via a facile sonochemical method in a surfactant/ligand-free system under ambient air. The as-prepared products are characterized by XRD, TEM, SAED, FE-SEM, HRTEM, and Raman spectroscopy. The effects of pH and ultrasound irradiation on the phase and morphology of the products are studied and the sonochemical formation mechanisms of 1D and 2D structures are discussed. TEM data from samples made after different reaction times suggest an ultrasound-induced nucleation and an oriented-attachment growth mechanism.
首次通过简便的声化学方法在无表面活性剂/配体的体系中于环境空气中成功合成了规则的磷酸铋纳米棒和氯氧化铋薄片。通过X射线衍射（XRD）、透射电子显微镜（TEM）、选区电子衍射（SAED）、场发射扫描电子显微镜（FE-SEM）、高分辨率透射电子显微镜（HRTEM）和拉曼光谱对所制备的产物进行了表征。研究了pH值和超声辐射对产物相和形貌的影响，并讨论了一维和二维结构的声化学形成机理。来自不同反应时间后制备的样品的TEM数据表明存在超声诱导成核和定向附着生长机制。
