用于在不锈钢基材上电化学合成 LaMnO3薄膜涂层的原料。为了提高掺杂镧系氧化物材料在荧光粉、荧光显示管或传热测量中的应用前景，人们开发了一种新的溶剂热法合成掺杂镧系氧化物 La2O2S 的方法。 Lanthanum(III) nitrate hydrate is a white crystalline solid that is highly soluble in water. It is also utilized in various fields such as catalysts, ceramics, and as a source of lanthanum ions in chemical synthesis. Application： Lanthanum(III) nitrate hydrate can be used: As a starting material to synthesize lanthanum zirconate nanoparticles. As a precursor to prepare luminescent lanthanum-tricarboxytriphenylamine (La-TCA) coordination polymer nanosheets. To fabricate perovskite oxide-type LaFeO3 dendrites for chemical sensors. To synthesize LaMnO3 perovskite catalysts by using citric acid sol–gel method and La0.6Sr0.4MnO3 perovskites via coprecipitation method. The LaMnO3 perovskite catalysts has used for the oxidation of propane for emission control of hydrocarbon volatile organic compounds.
