一般說明

乙酸钴(II)是一种结晶化合物，由于钴离子的存在，可与其它分子反应产生络合物。它广泛应用于催化、纳米材料合成和电镀。它也用作涂料和清漆的干燥剂，也可作为测试溶液中乙烯离子的试剂。

應用

醋酸钴（II）可用于：      
  • 作为前体，用于合成析氧反应中的氧化钴钛催化剂。     
  • 作为原料，用于制备用于碳纳米纤维生长的聚合物稳定的钴纳米催化剂的。   
  • 在温和反应条件下进行唑的直接胺化的催化剂。


醋酸钴（II）可以是：   
  • 在氧化锂钴（LiCoO2）的合成中用作钴源，LiCoO2可用作锂离子电池中的阴极材料。  
  • 用作前体，用于通过简单的直接热解过程合成氧化钴纳米颗粒。Co3O4纳米颗粒还可用作锂离子电池的高容量阳极材料。
  • 用作钙钛矿前体溶液中的添加剂，用于控制晶体生长并提高全屏幕可印刷无空穴传输材料（HTM）介孔钙钛矿太阳能电池（PSCs）的性能。

The morphology of metal oxide nanostructures influences the response of the materials in a given application. In addition to changing the composition, doping can also modify the morphology of a host nanomaterial. Herein, we determine the effect of dopant concentration

Despite the growing demand for hydrogen peroxide it is almost exclusively manufactured by the energy-intensive anthraquinone process. Alternatively, H2O2 can be produced electrochemically via the two-electron oxygen reduction reaction, although the performance of the state-of-the-art electrocatalysts is insufficient to meet
