Abstract
Q[8]-based honeycomb-like frameworks can be obtained in [AuCl4]--free aqueous HNO3 solution and aqueous HCl and HNO3 solutions that contain [AuCl4]-. The outer surface interaction of Q[8] with planar inorganic anions [AuCl4]- and NO3- is the main driving force. These frameworks exhibit a high selectivity for imprisoning [AuCl4]- that could establish a process for gold recovery.
摘要
在不含 [AuCl4]-的硝酸水溶液和含有 [AuCl4]-的盐酸和硝酸水溶液中可以得到基于 Q[8]的蜂窝状骨架。Q[8]与平面无机阴离子 [AuCl4]-和 NO3-的外表面相互作用是主要驱动力。这些骨架对捕获 [AuCl4]-表现出很高的选择性，这可以建立一个金回收的过程。
