摘要

Abstract > ONIOM(DFT:PM3) calculations were carried out to investigate and characterize possible acid sites of SAPO‐11 molecular sieve. Two functionals were employed: B3LYP and ωB97X‐D. This last functional includes dispersion effects that are absent in the former. Benzene, pyridine, and ammonia interaction energies as well as the OH stretching frequencies of the POH, SiOH, and bridged Si(OH)Al groups were used to characterize the acid sites. This work shows that the adsorption of benzene on the surface is as strong as the adsorptions inside main channel of SAPO‐11. Pyridine adsorption on the surface is weaker than the one corresponding to the main channel. NH <sub>3</sub> molecule interacts strongly with all OH groups or acid sites present in SAPO‐11. Moreover, the results reveal that it is possible to adsorb two NH <sub>3</sub> molecules at only one Br?nsted site. The adsorption of the second NH <sub>3</sub> molecule is energetically favorable mainly due to the hydrogen bond formation between the NH <sub>3</sub> molecules. In general the interaction energy increases with the type of functional used, according to the trend ωB97X‐D??B3LYP. The results show that ONIOM methodology seems to be suited to investigate the acid sites in SAPO‐11. </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><抽象类型= “主”> <标题类型= “主”>抽象</ TITLE> <P> ONIOM（DFT：PM3）的计算进行了调查和表征SAPO-11分子筛的可能酸位点。两函被雇用：B3LYP和ωB97X-d。这最后一个功能包含在前者缺席分散效果。苯，吡啶和氨相互作用能以及所述POH，SiOH基的OH伸缩的频率，和桥连的Si（OH）的Al基团进行了表征的酸位点。这项工作表明，在表面上苯的吸附是强如SAPO-11的主通道内的吸附。表面上吡啶吸附比对应于主信道的一个弱。 NH <子> 3 </子>强烈所有OH基团或酸性部位存在于SAPO-11分子相互作用。此外，结果表明，有可能吸附两个NH <子> 3 </子>仅在一个溴分子？nsted站点。第二NH <子>的吸附3 </子>分子是能量上有利的主要是由于NH <子> 3 </子>分子之间的氢键的形成。通常，与使用的功能的类型的相互作用能量的增加，根据趋势ωB97X-d＆有B3LYP。结果表明，ONIOM方法似乎是适用于调查SAPO-11的酸位。 </ 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-21753/'>《International Journal of Quantum Chemistry》</a> <b style="margin: 0 2px;">|</b><span>2018年第11期</span><b style="margin: 0 2px;">|</b><span>共12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=Sierraalta Anibal&option=202" target="_blank" rel="nofollow">Sierraalta Anibal;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=A?ez Rafael&option=202" target="_blank" rel="nofollow">A?ez Rafael;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Coll David S.&option=202" target="_blank" rel="nofollow">Coll David S.;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Alejos Paola&option=202" target="_blank" rel="nofollow">Alejos Paola;</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>Laboratorio de Química Física y Catálisis Computacional Departamento de Química Centro de Química Instituto Venezolano de Investigaciones Científicas Apartado 21827Caracas 1020‐A Venezuela;</p> <p>Laboratorio de Química Física y Catálisis Computacional Departamento de Química Centro de Química Instituto Venezolano de Investigaciones Científicas Apartado 21827Caracas 1020‐A Venezuela;</p> <p>Laboratorio de Físico Química Teórica de Materiales Departamento de Química Instituto Venezolano de Investigaciones CientíficasVenezuela;</p> <p>Laboratorio de Química Física y Catálisis Computacional Departamento de Química Centro de Química Instituto Venezolano de Investigaciones Científicas Apartado 21827Caracas 1020‐A Venezuela;</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/1186.html" title="物理化学（理论化学）、化学物理学">物理化学（理论化学）、化学物理学;</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=acid sites&option=203" rel="nofollow">acid sites;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=adsorption&option=203" rel="nofollow">adsorption;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=ωB97X‐D&option=203" rel="nofollow">ωB97X‐D;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=ONIOM&option=203" rel="nofollow">ONIOM;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=SAPO‐11&option=203" rel="nofollow">SAPO‐11;</a> </p> <div class="translation"> 机译：酸部位;吸附;ωb97x-d;oniom;sapo-11;
