Experimental methods in chemical engineering: Fourier transform infrared spectroscopy—FTIR

摘要

Abstract > When molecules absorb infrared radiation (IR), their vibrational mode—stretching and bending of the electric dipole—changes to an excited state. Functional groups in organic molecules absorb IR related to their characteristic vibrational modes. A Fourier transform infrared absorption (FTIR) analyzer measures the absorbed IR to identify molecular composition of surfaces, structural and geometric isomers, orientation in polymers and solutions, and quantify impurities. We describe the power of FTIR instruments and their basic operating principles, including the main experimental setups available: transmission, diffuse reflectance (DRIFTS), reflection adsorption infrared spectroscopy (RAIRS), and attenuated total reflection (ATR), including the recent advances related to time‐resolved and operando applications. In catalytic studies, FTIR spectroscopy has demonstrated its versatility over the last several decades to understand reaction mechanisms, measure gas phase composition, and identify active sites. Over 3000 articles include catalysis and FTIR as keywords but 50?000 articles per year mention IR. We generated a bibliometric map of keywords in articles that Web of Science indexed in 2016 and 2017. The map identified four broad clusters of research related to or applying FTIR: nano‐composites, composites, and mechanical properties; nano‐particles, degradation, graphene oxide, and photo‐catalysis; adsorption, aqueous solutions, and waste water; and drug delivery, silver and gold nano‐particles, green synthesis, and antibacterial activity. Together with a synopsis of the principals of IR spectroscopy and a review of the applications, we discuss uncertainties and limitations of the technique. </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> > 当分子吸收红外辐射（IR）时，它们的振动模式拉伸和电偶极子的弯曲变为激发状态。有机分子中的官能团吸收与其特征振动模式相关的IR。傅里叶变换红外吸收（FTIR）分析仪测量吸收的IR，识别表面，结构和几何异构体的分子组成，聚合物和溶液中的取向，以及量化杂质。我们描述了FTIR仪器的力量及其基本操作原理，包括可用的主要实验设置：传输，漫反射率（漂移），反射吸附红外光谱（河数），以及减毒的全反射（ATR），包括最近与之相关的进步时间解决和Operando应用程序。在催化研究中，FTIR光谱证明了过去几十年来理解反应机制，测量气相组合物和鉴定活性位点的通用性。超过3000篇文章包括催化作用和FTIR作为关键词，但每年50件物品提及IR。我们在文章中生成了一个关键词的生物计数图科学网络</ i> 在2016年和2017年索引。该地图确定了与FTIR或应用FTIR：纳米复合材料，复合材料和机械性能有关的四个广泛的研究群;纳米颗粒，降解，石墨烯和光催化;吸附，水溶液和废水;和药物递送，银和金纳米颗粒，绿色合成和抗菌活性。我们与IR光谱的主体的概要以及审查申请，讨论了该技术的不确定性和局限性。 </ 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-30631/'>《The Canadian Journal of Chemical Engineering》</a> <b style="margin: 0 2px;">|</b><span>2020年第1期</span><b style="margin: 0 2px;">|</b><span>共9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/238.html" title="化学工业">化学工业;</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=catalysis&option=203" rel="nofollow">catalysis;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=DRIFTS&option=203" rel="nofollow">DRIFTS;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Fourier transform infrared&option=203" rel="nofollow">Fourier transform infrared;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=nanoparticles&option=203" rel="nofollow">nanoparticles;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=vibrational modes&option=203" rel="nofollow">vibrational modes;</a> </p> <div class="translation"> 机译：催化;漂移;傅里叶变换红外;纳米粒子;振动模式; </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/0704024776135.html">Experimental methods in chemical engineering: Fourier transform infrared spectroscopy—FTIR</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-30631/" target="_blank" rel="nofollow" class="tuijian_authcolor">The Canadian Journal of Chemical Engineering .</a> <span>2020</span><span>,第1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：化学工程实验方法：傅里叶变换红外光谱 - FTIR</span> </p> </li> <li> <div> <b>2. </b><a class="enjiyixqcontent" href="/academic-journal-foreign_detail_thesis/0204119397580.html">0561 Lipolysis effect on milk fat and protein analysis by infrared spectroscopy using filter and Fourier transform infrared (FTIR) methods.</a> <b>[J]</b> . <span> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Fonseca?L.
