Direct Crystallization of Layered Silicates on the Surface of Amorphous Silica

Okada Tomohiko

摘要

Abstract > We overview the entire surface coverage of amorphous silica with layered silicates (smectite‐like) using the direct crystallization technique under hydrothermal conditions. Various shapes (e.?g., microspheres, fibers, microcapsules) have been available as the silica substrates, which involve partial dissolution triggered by the hydrolysis of urea for supplying a source of the layered silicates. Other sources (e.?g., Li + , Mg 2+ , Al 3+ ) have been supplied from aqueous solutions, participating the heterogeneous nucleation of the layered silicates. Because of partial dissolution of the silica substrates, the original shape has been preserved after the hydrothermal reactions. Cation exchange reactions, usually observed for conventional smectite systems, occurred by replacing the interlayer cations in the silicates with metal (a rare‐earth ion) and organic (a quaternary long‐chain alkylammonium, methylene blue, and a tris‐chelated complex) cations. We have discussed the mechanism of the crystallization and displayed some applications of the hybrids (e.?g., chiral discrimination, filtering, and magnetic recovery). </abstract> </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display: none;">展开▼</span> </div> <div class="translation abstracttxt"> <span class="zhankaihshouqi fivelineshidden" id="abstract"> <span>机译：</span><Abstract Type =“Main”XML：Lang =“en”> <标题类型=“main”>抽象</ title> >我们概述了使用分层硅酸盐（蒙片石）的整体表面覆盖水热条件下的直接结晶技术。各种形状（例如，微球，纤维，微胶囊）可用作二氧化硅底物，其涉及通过尿素的水解而引发的部分溶解，以供应层状硅酸盐的源。其他来源（E.?g，Li + </ sup>，Mg 2 + </ sup>，Al 3 + </ sup>）已从水溶液中提供，参与层状硅酸盐的异质成核。由于二氧化硅基材的部分溶解，在水热反应后已经保留了原始形状。通常观察到常规蒙脱石体系的阳离子交换反应，通过用金属（稀土离子）和有机（季长链烷基烷基铵，亚甲基蓝色和Tris-Chelated Chical）阳离子替换硅酸盐中的层间阳离子而发生。我们已经讨论了结晶的机制，并显示了杂种的一些应用（例如，手性歧视，过滤和磁性恢复）。 </ p> </ abstract> </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display: none;">展开▼</span> </div> </div> <div class="record"> <h2 class="all_title" id="enpatent33" >著录项</h2> <ul> <li> <span class="lefttit">来源</span> <div style="width: 86%;vertical-align: text-top;display: inline-block;"> <a href='/journal-foreign-16132/'>《Chemical record》</a> <b style="margin: 0 2px;">|</b><span>2018年第8期</span><b style="margin: 0 2px;">|</b><span>共11页</span> </div> </li> <li> <div class="author"> <span class="lefttit">作者</span> <p id="fAuthorthree" class="threelineshidden zhankaihshouqi"> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Okada Tomohiko&option=202" target="_blank" rel="nofollow">Okada Tomohiko;</a> </p> <span class="z_kbtnclass z_kbtnclassall hoverxs" id="zkzz" style="display: none;">展开▼</span> </div> </li> <li> <div style="display: flex;"> <span class="lefttit">作者单位</span> <div style="position: relative;margin-left: 3px;max-width: 639px;"> <div class="threelineshidden zhankaihshouqi" id="fOrgthree"> <p>Department of Chemistry and Materials EngineeringShinshu University 4-17-1 WakasatoNagano 380-0928 Japan;</p> </div> <span class="z_kbtnclass z_kbtnclassall hoverxs" id="zhdw" style="display: none;">展开▼</span> </div> </div> </li> <li > <span class="lefttit">收录信息</span> <span style="width: 86%;vertical-align: text-top;display: inline-block;"></span> </li> <li> <span class="lefttit">原文格式</span> <span>PDF</span> </li> <li> <span class="lefttit">正文语种</span> <span>eng</span> </li> <li> <span class="lefttit">中图分类</span> <span><a href="https://www.zhangqiaokeyan.com/clc/159.html" title="化学">化学;</a></span> </li> <li class="antistop"> <span class="lefttit">关键词</span> <p style="width: 86%;vertical-align: text-top;"> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=hydrothermal synthesis&option=203" rel="nofollow">hydrothermal synthesis;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=silicate&option=203" rel="nofollow">silicate;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=layered compounds&option=203" rel="nofollow">layered compounds;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=intercalation&option=203" rel="nofollow">intercalation;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=crystal growth&option=203" rel="nofollow">crystal growth;</a> </p> <div class="translation"> 机译：水热合成;硅酸盐;层状化合物;嵌入;晶体生长;
