乙氧醇铌（V）是一种金属有机化合物，在溶液中发射二聚化反应形成 Nb2(OEt)10 分子。在室温下，它是一种无色液体，可与一些有机溶剂混溶，但是也易于水解。在0.1 mmHg压力下乙氧醇铌（V）在 5 °C下凝固，在142 °C 下沸腾。它可以通过在氯化四乙基铵（TEAC）导电添加存在的情况下乙醇与铌板和不锈钢电极的电化学反应来合成。
用途：
乙氧醇铌（V）可作为前体合成氧化铌, 如Nb2O5 、 NaNbO3 和TiNb2O7。乙氧醇铌（V）常用于胶体溶液基合成，如溶胶凝胶处理和电纺丝。这些化学性质使得研究者可以控制微观结构，以生成凝胶 、纳米纤维、纳米管和微球。 乙氧醇铌（V）通常也可添加在其它金属醇盐中，从而使金属氧化物（最常见的是二氧化钛）掺杂铌。
由于其低沸点和低分解温度（~325-350 °C），乙氧醇铌（V）也可作为前体用于氧化铌的原子层沉积、化学气相沉积和金属有机化学气相沉积。
它也可作为掺杂剂用于制备染料敏化太阳能电池（DSSC）中的铌掺杂TiO2光阳极。铌的掺杂降低了TiO2的导带，改善了TiO2光阳极的电子注入和转移能力。这导致DSSC性能显著提升。
Niobium(V) ethoxide is a metal-organic compound that dimerizes in solution to form Nb2(OEt)10 molecules. At room temperature, it is a colorless liquid that is miscible with some organic solvents, but which hydrolyzes readily. Niobium(V) ethoxide freezes at 5 °C and boils at 142 °C at 0.1 mmHg. It can be synthesized by the electrochemical reaction of ethanol with niobium plate and stainless-steel electrodes in the presence of tetraethylammonium chloride (TEAC) as the conductive additive.
Purpose
Niobium(V) ethoxide is a synthetic precursor for niobium oxides, for example Nb2O5 , NaNbO3 , andTiNb2O7. Niobium(V) ethoxide is commonly used in colloidal solution-based syntheses like sol-gel processing and electrospinning. These chemistries allow researchers to control the microstructure to form gels , nanofibers , nanotubes , and microspheres. Niobium(V) ethoxide is also commonly added to other metal alkoxides to dope metal oxides, most commonly titania, with niobium. Because of its low boiling point and low decomposition temperature (~325-350 °C),niobium(V) ethoxide is also used as a precursor in atomic-layer deposition, chemical vapor deposition, and metal-organic chemical vapor deposition of niobium oxides. It can also be used as a dopant to prepare Nb-doped TiO2 photoanode for dye-sensitized solar cells (DSSC). The doping of Nb lowers the conduction band of TiO2 enhancing electron injection and transfer ability of TiO2 photoanode. This results in a significant increase in the performance of DSSC.
