three-dimensional (3D) structures of layered zinc hydroxides (LZHs) were synthesized via a hydrothermal method. During the process, two kinds of LZHs with different crystal structures could be formed, depending on the ionic groups intercalated in zinc hydroxide layers: when carbonate anions were the only interlayer ions, the corresponding LZH compound was assigned as LZHC or zinc hydroxide carbonate; when the interlayer
通过水热法合成了一系列层状的氢氧化锌(LZHs)的均匀一致的三维(3D)结构。在该过程中,根据插入氢氧化锌层中的离子基团,可以形成两种具有不同晶体结构的LZHs:当碳酸根阴离子是唯一的层间离子时,相应的LZH化合物被指定为LZHC或碳酸氢锌;当层间离子同时包含碳酸根阴离子和长链季铵基团时,相应的LZH化合物称为LZHDC。有趣的是,LZHDC通过涉及碳酸盐阴离子交换长链季铵基团的结构和组成转变而转变为LZHC。我们提出一个逐步的增长和阴离子交换机制,涉及从锌前体到LZHDC到LZHC的转化。我们证明了实用程序在过程中获得的LZHs作为通过热解形成新型3D ZnO结构的自我牺牲模板。
