Abstract

The Front Cover illustrates the controlled incorporation of magnesium atoms into a partially dealuminated BEA zeolite, to be used as catalyst in the methanol-to-hydrocarbon reaction. Thanks to this variation in the catalyst's active environment, the chemical properties of the catalyst have been modified. This results in a higher production of olefins (propylene and butylene, as can be observed), driven by the promotion of the olefinic cycle mechanism. Additionally, the catalyst's lifetime is improved, as represented by the hourglass in the background. More information can be found in the Research Article by J. Ruiz Martínez and co-workers (DOI: 10.1002/cctc.202500151).

封面:Lewis酸位点对mg脱铝BEA沸石上甲醇制烃催化剂寿命的影响(ChemCatChem 13/2025)
封面说明了镁原子被控制的结合到部分脱铝BEA沸石中,用作甲醇-烃反应的催化剂。由于催化剂活性环境的这种变化,催化剂的化学性质被改变了。这导致烯烃(丙烯和丁烯,可以观察到)的更高产量,推动了烯烃循环机制的促进。此外,催化剂的寿命得到了改善,如背景中的沙漏所示。更多信息可以在J. Ruiz Martínez及其同事的研究文章中找到(DOI: 10.1002/cctc.202500151)。

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.
