二氧化钛(TiO2(B))是TiO2的亚稳态多晶型之一，以H2SO4为添加剂，通过甘醇酸过氧钛络合物([Ti-4(C2H2O3)(4)(C2H3O3)(2)(O-2)(2)](6)的水热反应制备了二氧化钛(TiO2(B))。通过X射线衍射(XRD)、拉曼光谱和透射电子显微镜(TEM)表征表明，所得粉末具有良好的稳定性。棒状单相 TiO2(B)，TiO2(B) 的粒径和长径比可通过所制备粉末样品的后合成水热晶体生长 (PHCG) 来控制 (C) 2008 Elsevier B.V. 保留所有权利。
Titanium dioxide (TiO2(B), one of metastable polymorphs of TiO2 was prepared by hydrothermal reaction of glycolato peroxotitanium complex ([Ti-4(C2H2O3)(4)(C2H3O3)(2)(O-2)(2)](6) in the presence of H2SO4 as an additive. Characterization by X-ray diffraction (XRD), Raman spectroscopy, and transmission electron microscopy (TEM) revealed that the obtained powders were single-phase TiO2(B) with rod-like shape, Particle size and aspect ratio of TiO2(B) can be controlled by post-synthetic hydrothermal crystal growth (PHCG) of the as-prepared powder sample.
