一般描述

六水合硝酸钴是一种无机化合物，可溶于水。它用作合成含钴陶瓷材料（如钴铁氧体和钴掺杂二氧化钛）的前驱体，这些材料具有磁性、电学和光催化特性。此外，由于其氧化还原活性，它在电化学应用中也得到应用，例如在锂离子电池阴极和燃料电池催化剂中。

应用

六水合硝酸钴可用于：      
  • 通过直接热分解法合成纳米-Co3O4 作为电化学水氧化应用的前驱体
  • 通过溶胶-凝胶法合成具有可控形貌的单晶 Co3O4 粉末，用于锂离子电池应用。      通过溶胶-凝胶法合成具有受控尺寸、形状和形貌的含钴纳米材料，例如纳米-Co3O4。      
  • 作为重要的前驱体，利用共沉淀法生成用于锂离子电池的富镍阴极材料（NMC、NCA），因为该方法简单、易于放大，并且能够在颗粒尺度上产生均匀的结构。

六水合硝酸钴可用作：      
  • 制备钴基纳米材料和钴配合物的起始原料。      
  • 催化剂，通过三组分缩合反应合成 5-羧基苯胺二氢嘧啶酮衍生物。     
  • 掺杂剂，制备用于高温应用的 LaCr1−xCoxO3 固溶体陶瓷。

特点和优势

  • 高纯度，痕量金属分析（=< 15 ppm），适用于电池。     
  • 高水溶性，非常适合合成用于各种应用的复合材料。
  • 金属离子（包括 Al、K、Na、Mg、Cu、Co 等）的 ppm 含量很低。
