中文摘要：
以四氟化钛为前驱物、P123为表面活性剂、柠檬酸为稳定剂、盐酸为酸性调节剂、氟化铵为添加剂，利用水热方法首次制备出暴露{111}面的截顶点四棱双锥锐钛矿多面体．通过XRD，SEM，TEM，HRTEM，SEAD和EDX对所制备的多面体的组成、结构和形貌进行了分析和表征．结果显示：柠檬酸和氟化铵的使用，有利于锐钛矿多面体的取向生长和{111}晶面的保留．同时研究发现，所制备的多面体在碱性和紫外光照条件下对亚甲基蓝（MB）具有很好的催化活性和降解效果，显示出潜在的应用价值．
英文摘要：
Polyhedrons of truncated anatase bipyramids with exposure of { 111 } facets were hydrothermally synthesized from hydrolysis of TiF4 in the presence of NH4F, HC1, and tri-block copolymer P123 using citric acid monohydrate as a stabilizer. The phase, crystal structure, morphology, chemical composition and property of the anatase polyhedrons were characterized by various techniques of X-ray diffraction （XRD）, transmission electron microscopy （TEM）, high- resolution transmission electron microscopy （HRTEM）, scanning electron microscopy （SEM）, selected area electron diffraction （SEAD）, energy-dispersive Xray spectrometry （EDX） and UV radiations, and their high performances in photo-degradation of methylene blue （MB） under alkaline conditions were specifically recognized.
