一般描述
六水硝酸铈(III)是一种白色到黄色结晶盐,具有吸湿性和气敏性。六水硝酸铈(III)极易溶于水、乙醇和丙酮。六水硝酸铈(III)可在57°C融化,在190 °C开始热分解,并在400°C时完全分解为氧化物。
应用
六水硝酸铈(III)作为铈的一种来源,尤其应用于合成微型或纳米结构的二氧化铈(氧化铈)。研究人员利用六水硝酸铈(III)的高溶解度和低分解温度,在水热反应、溶胶-凝胶加工和共沉淀/煅烧反应中合成氧化铈和铈化合物。例如,在一项研究中,材料科学家通过共沉淀和煅烧硝酸铈和乙酸钴制备一种二维钴掺杂氧化铈纳米片。再例如,研究人员利用硝酸铈的高溶解度特性,生成二维稀土双钙钛矿晶体。 此外,研究人员还使用硝酸铈形成复合材料,如石墨烯-氧化铈纳米颗粒复合材料和TiO2/CeO2纳米复合材料、利用铈’(III/IV)氧化还原化学反应进行光吸收和光催化作用。在一项展示硝酸铈化学作用的成熟材料工程的研究中,使用钙掺杂的铈纳米管复合物与双(三氟甲烷磺酰基)亚氨基锂(LiTFSI)用作固态锂离子电解质。与未掺杂Ca-CeO2相比,CeO2纳米管具有更高浓度的氧空位。该纳米管由硝酸铈和硝酸钙溶液与聚乙烯吡咯烷酮共混物制备而成,最终在煅烧过程中通过热解去除。
