Abstract

The Front Cover shows the encapsulation of Ni species inside hollow ZSM-5 zeolite cages, emphasizing their role in ethylene oligomerization. The hollow structure isolates Ni²⁺ active sites while reducing Brønsted acidity, promoting selective dimerization through the Cossee-Arlman mechanism. This unique catalyst allows us to work in intrinsic conditions and develop a microkinetic model to understand the reaction mechanisms and rates. More information can be found in the Research Article by S. Vernuccio, P. Castano and co-workers (DOI: 10.1002/cctc.202500957).

封面：无br ø nstede中空ZSM-5沸石包封Ni的乙烯寡聚选择性和微动力学见解（ChemCatChem 18/2025）

封面展示了Ni物种在中空ZSM-5沸石笼中的封装，强调了它们在乙烯低聚反应中的作用。中空结构分离Ni2+活性位点，降低Brønsted酸性，通过Cossee-Arlman机制促进选择性二聚化。这种独特的催化剂使我们能够在固有条件下工作，并开发微动力学模型来了解反应机制和速率。更多信息可以在S. Vernuccio， P. Castano及其同事的研究文章中找到（DOI: 10.1002/cctc.202500957）。

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.
