Abstract

MxOy nanometric powders (Nb2O5, In2O3, and ZrO2) have been efficiently synthesized at low temperatures with the use of simple precursors and with no acid or base catalysis or stabilizing agents. The powders have been characterized by Thermogravimetry/Differential Thermal Analysis, X-ray diffraction, and scanning electron microscopy. The oxides obtained have well-defined crystalline structures, exhibit homogeneity, and crystallite sizes ranging from 9 to 16 nm in diameter.

摘要

通过使用简单的前驱体，在无酸或碱催化以及无稳定剂的情况下，已在低温下高效合成了MxOy纳米粉末（Nb2O5、In2O3和ZrO2）。通过热重分析/差示热分析、X射线衍射和扫描电子显微镜对这些粉末进行了表征。所获得的氧化物具有明确的晶体结构，表现出均匀性，并且微晶尺寸直径范围为9至16纳米。
