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).

期刊介绍： With an impact factor of 4.495 (2018), ChemCatChem is one of the premier journals in the field of catalysis. The journal provides primary research papers and critical secondary information on heterogeneous, homogeneous and bio- and nanocatalysis. The journal is well placed to strengthen cross-communication within between these communities. Its authors and readers come from academia, the chemical industry, and government laboratories across the world. It is published on behalf of Chemistry Europe, an association of 16 European chemical societies, and is supported by the German Catalysis Society.
