摘要
封面描绘了乙醇在双功能催化剂作用下转化为正丁醇的过程，以及利用探针分子和光谱分析催化位点的方法。Wei Tian 和 José Herrera 结合使用了原位傅立叶变换红外光谱、二氧化碳-热致发射光谱和操作滴定法，利用二氧化碳和乙酸来识别和量化催化 C-C 偶联的相关官能团。他们的研究结果表明，MgAlO 系统催化的正丁醇形成是由α-碳质子抽取调节的，而α-碳质子抽取只发生在强碱性中心上。更多信息可参阅 Wei Tian 和 José E. Herrera 的研究文章（DOI: 10.1002/cctc.202400225）。
Front Cover: Catalytic Relevance of Mg-Al-O Basic Centers in the Upgrade of Ethanol to n-Butanol (ChemCatChem 19/2024)
The Front Cover depicts the stages ethanol follows during its conversion to n-butanol over a bifunctional catalyst, and the use of probe molecules and spectroscopy to interrogate catalytic sites. Applying a combination of in-situ FTIR, CO2-TPD, and operando titration, Wei Tian and José Herrera use carbon dioxide and acetic acid to identify and quantify catalytically relevant functionalities responsible for C–C couplings. Their findings indicate n-butanol formation catalyzed by MgAlO systems is regulated by α-carbon proton abstraction taking place only over strong basic centers. More information can be found in the Research Article by Wei Tian and José E. Herrera (DOI: 10.1002/cctc.202400225).
