Abstract Novel glycolate precursors to metal titanates MTiO3 (M = Ni2+, Co2+, Zn2+) were synthesized by heating metal acetate and titanium isopropoxide in ethylene glycol up to 190 °C during distilling the water to avoid hydrolysis of precursors. These glycolate precursors were characterized by X-ray diffraction (XRD), Fourier transformation infrared spectroscopy (FT-IR), thermal analysis (TG-DTA), and scanning electron microscopy (SEM). The obtained three isostructural glycolate precursors were containing metal (Ni, Co, Zn), titanium, and ethylene glycol with a ratio of 1:1:4. The crystal growth processes of three precursors were different from each other. These precursors revealed homogeneous and well-defined rod-like structure with 0.5–3.0 μm in thickness and 4–20 μm in length. The obtained metal titanates were consisted of microrods with 0.4–1.5 μm in thickness and 2–15 μm in length.

MTiO 3 (M = Ni 2+ , Co 2+ , Zn 2+ )乙醇酸盐前体的合成和表征

摘要 通过在蒸馏水期间将金属乙酸盐和异丙醇钛在乙二醇中加热至 190 °C 以避免前体水解，合成了金属钛酸盐 MTiO3 (M = Ni2+, Co2+, Zn2+) 的新型乙醇酸盐前体。这些乙醇酸酯前体通过 X 射线衍射 (XRD)、傅里叶变换红外光谱 (FT-IR)、热分析 (TG-DTA) 和扫描电子显微镜 (SEM) 进行表征。得到的三种同构乙醇酸盐前驱体分别含有金属（Ni、Co、Zn）、钛和乙二醇，比例为1:1:4。三种前驱体的晶体生长过程彼此不同。这些前体显示出均匀且界限分明的棒状结构，厚度为 0.5-3.0 μm，长度为 4-20 μm。获得的金属钛酸盐由0.4-1的微棒组成。
