该报告详细介绍了V形SnO 2纳米棒的制备，臂之间的角度为112.1°。通过在NaCl助熔剂中加热1，10菲咯啉（phen）封端的Sn纳米颗粒（2 - 5 nm）来制备纳米棒。phen和NaCl助熔剂的使用是形成长V形结构不可缺少的。通过XRD、SEM、TEM和HRTEM表征，证实了纳米棒为结晶SnO 2，在V结处具有孪晶结构（孪晶面为（101），孪晶方向为[101]）。纳米棒的直径几乎是单分散的，平均值为48.4和13.2 nm，这取决于合成条件。
This report details the preparation of V-shaped SnO2 nanorods with an angle of 112.1° between the arms. The nanorods were produced by heating 1,10 phenanthroline (phen)-capped Sn nanoparticles (2−5 nm) in a NaCl flux. The use of both phen and NaCl flux were indispensable in forming long V-shaped structures. XRD, SEM, TEM, and HRTEM characterizations of the nanorods confirmed that the rods were crystalline SnO2 with a twin structure (twin plane of (101) and twin direction of [101]) at the V-junction. The diameters of the nanorods were nearly monodispersed with mean values of 48.4 and 13.2 nm depending on the synthesis conditions.
