A Universal Nano‐capillary Based Method of Catalyst Immobilization for Liquid‐Cell Transmission Electron Microscopy

摘要

Abstract > A universal nano‐capillary based method for sample deposition on the silicon nitride membrane of liquid‐cell transmission electron microscopy (LCTEM) chips is demonstrated. It is applicable to all substances which can be dispersed in a solvent and are suitable for drop casting, including catalysts, biological samples, and polymers. Most importantly, this method overcomes limitations concerning sample immobilization due to the fragility of the ultra‐thin silicon nitride membrane required for electron transmission. Thus, a straightforward way is presented to widen the research area of LCTEM to encompass any sample which can be externally deposited beforehand. Using this method, Ni <sub> x </sub> B nanoparticles are deposited on the μm‐scale working electrode of the LCTEM chip and in?situ observation of single catalyst particles during ethanol oxidation is for the first time successfully monitored by means of TEM movies. </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> > 对液体细胞透射电子显微镜（LCTEM）芯片的氮化硅膜上的样品沉积的通用纳米毛细管基于方法。它适用于可以分散在溶剂中的所有物质，并且适用于液滴铸造，包括催化剂，生物样品和聚合物。最重要的是，该方法由于电子传输所需的超薄氮化硅膜的脆弱性而克服了样品固定的限制。因此，提出了一种直接的方式以扩展Lctem的研究区域以包括可以预先外部沉积的任何样品。使用此方法，ni <sub> x </ i> </ sub> B纳米颗粒沉积在Lctem芯片的μm级工作电极上，并且在乙醇氧化过程中单个催化剂颗粒的原位观察是通过TEM电影成功监测的第一次。 </ p> </摘要> </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-19011/'>《Angewandte Chemie》</a> <b style="margin: 0 2px;">|</b><span>2020年第14期</span><b style="margin: 0 2px;">|</b><span>共5页</span> </div> </li> <li> <div class="author"> <span class="lefttit">作者</span> <p id="fAuthorthree" class="threelineshidden zhankaihshouqi"> </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"> </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/1188.html" title="应用化学">应用化学;</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=electrocatalysis&option=203" rel="nofollow">electrocatalysis;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=ethanol oxidation&option=203" rel="nofollow">ethanol oxidation;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=liquid-cell TEM&option=203" rel="nofollow">liquid-cell TEM;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=nano electrochemistry&option=203" rel="nofollow">nano electrochemistry;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=nickel boride&option=203" rel="nofollow">nickel boride;</a> </p> <div class="translation"> 机译：电殖分析;乙醇氧化;液体细胞温度;纳米电化学;硼化镍; </div> </li> </ul> </div> </div> <div class="literature cardcommon"> <div class="similarity "> <h3 class="all_title" id="enpatent66">相似文献</h3> <div class="similaritytab clearfix"> <ul> <li class="active" >外文文献</li> <li >中文文献</li> <li >专利</li> </ul> </div> <div class="similarity_details"> <ul > <li> <div> <b>1. </b><a class="enjiyixqcontent" href="/journal-foreign-detail/0704028162423.html">A Universal Nano‐capillary Based Method of Catalyst Immobilization for Liquid‐Cell Transmission Electron Microscopy</a> <b>[J]</b> . <span> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=&option=202" target="_blank" rel="nofollow" class="tuijian_auth tuijian_authcolor"> </a> <a href="/journal-foreign-19011/" target="_blank" rel="nofollow" class="tuijian_authcolor">Angewandte Chemie .</a> <span>2020</span><span>,第14期</span> </span> </div> <p class="zwjiyix translation" style="max-width: initial;height: auto;word-break: break-all;white-space: initial;text-overflow: initial;overflow: initial;"> <span>机译：液体细胞透射电子显微镜催化剂固定催化剂固定化通用纳米毛细管</span> </p> </li> <li> <div> <b>2. </b><a class="enjiyixqcontent" href="/journal-foreign-detail/0704028130115.html">Nanoparticle Immobilization for Controllable Experiments in Liquid-Cell Transmission Electron Microscopy</a> <b>[J]</b> . <span> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Robertson Alex W.&option=202" target="_blank" rel="nofollow" class="tuijian_auth tuijian_authcolor">Robertson Alex W.,</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Zhu Guomin&option=202" target="_blank" rel="nofollow" class="tuijian_auth tuijian_authcolor">Zhu Guomin,</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Mehdi B.
