Abstract Selective deintercalation of Ag+-ion from AgFeO2 and AgCrO2 with the use of dilute aqueous solutions of NH4Cl was achieved successfully. Based on the ICP analysis, the Ag: Fe and Ag: Cr ratios were 0.9:1 and 0.87:1 in the deintercalated sample of AgFeO2 and AgCrO2, respectively. Retention of both structure and the polytypes were noticed after deintercalation together with the reduction in their unit cell c-axis. Raman spectra of deintercalated samples confirmed the preservation of overall symmetry. XPS results confirmed the existence of Fe (III) and Cr (III) in the Ag+-ion deintercalated samples.

从金铁矿 AgFeO2 和 AgCrO2 中软化学脱嵌银

摘要 利用NH4Cl 的稀水溶液成功地实现了AgFeO2 和AgCrO2 中Ag+离子的选择性脱嵌。根据 ICP 分析，AgFeO2 和 AgCrO2 脱嵌样品中的 Ag:Fe 和 Ag:Cr 比率分别为 0.9:1 和 0.87:1。在脱嵌后注意到结构和多型体的保留以及它们的晶胞 c 轴的减少。脱嵌样品的拉曼光谱证实了整体对称性的保持。XPS 结果证实了在 Ag+ 离子脱嵌样品中存在 Fe (III) 和 Cr (III)。
