AgReO4 nanoplates and micron-sized AgReO4 rods and stars are obtained for the first time from controlled particle growth in THF. [NBu4][ReO4] or [NMe4][ReO4] and Ag(OTf) (OTf: triflate) are used as the starting materials. The crystal growth is directed by the presence (i.e., plates) or absence (i.e., rods, stars) of trioctylphosphine (TOP) as a coordinating agent as well as by the temperature of the
AgReO4 纳米片和微米尺寸的 AgReO4 棒和星是首次从 THF 中受控的粒子生长中获得。[NBu4][ReO4] 或 [NMe4][ReO4] 和 Ag(OTf)(OTf:三氟甲磺酸盐)用作起始材料。晶体生长由作为配位剂的三辛基膦(TOP)的存在(即,板状)或不存在(即棒状、星状)以及反应温度(即回流的 THF 中的板状、棒状;室温下的星星)。总之,各个形态的增长可归因于溶解的 Ag+ 的可用性和扩散速率,其受反应温度和 TOP 的存在影响。不同形状的 AgReO4 颗粒通过扫描电子显微镜 (SEM)、X 射线衍射分析 (XRD) 和傅里叶变换红外 (FT-IR) 光谱进行表征。
