Abstract

The Cover Feature shows how a combined approach of spectroscopy and performance testing of the phosphorus blocking on industrial vanadyl pyrophosphate catalysts reveals that the critical active sites for n-butane activation consist of unsaturated V⁴⁺ centers and Brønsted acid P─OH groups linked by V─O─P bridges. Remarkably, only 11% of the N2-accessible catalyst surface is active. High phosphorus loadings generate β-VO(PO₃)₂, which boosts activity but compromises selectivity. More information can be found in the Research Article by G. Mestl and co-workers (DOI: 10.1002/cctc.202500077).

封面专题：环状工业焦磷酸钒基马来酸酐催化剂活性中心的鉴定（ChemCatChem 13/2025）

Cover Feature展示了工业焦磷酸钒基催化剂上磷阻断的光谱和性能测试相结合的方法，揭示了正丁烷活化的关键活性位点由不饱和V4+中心和由V─O─P桥连接的Brønsted酸P─OH基团组成。值得注意的是，只有11%的n2可触及的催化剂表面是活跃的。高磷负荷产生β-VO(PO3)2，它提高活性，但损害选择性。更多信息可以在G. Mestl及其同事的研究文章中找到（DOI: 10.1002/cctc.202500077）。

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.
