一般描述

六水合氯化钴(II),一种氯化钴的水合物形式,用于电镀和催化剂制备。它作为锂离子电池电极材料合成的前驱体,并在包括乙酰化、醇的甲苯磺酰化和缩合反应在内的一系列有机反应中充当催化剂。

应用

六水合氯化钴(II)可用作:      
  • 钙钛矿太阳能电池电子传输层(ETL)的添加剂,以提高其性能,特别是通过减少能量损失和增加开路电压。      
  • ZnO纳米结构的钴源。钴离子掺入ZnO基质对于改变其电子和光学特性至关重要。      
  • 用于修饰钴金属有机框架(Co-MOF)衍生的碳微球的前驱体,作为锂离子电池中的负极材料。

We developed a novel stabilized nanoscale zerovalent iron (NZVI) particles with Ni using an electron conducting polymer, polyvinylpyrrolidone (PVP), to selectively dechlorinate trichloroethylene (TCE) to non-toxic intermediates. The size of the PVP stabilized NZVI-Ni ((PVP-NZVI-Ni), average diameter: ∼20nm) is smaller

High-performance catalysts for the oxygen-evolution reaction in water electrolysis are usually based on expensive and rare elements. Herein, mixed-metal borides are shown to be competitive with established electrocatalysts like noble metal oxides and other transition-metal(oxide)-based catalysts. Iron incorporation into nanoscale
