Abstract
The synthesis of atomically precise cluster catalysts has emerged as a central theme in this field, as it represents an effective approach to uncover the origins of catalytic reactivity. In this study, we have prepared supported PtN cluster catalysts (N = 1,2,3,923 ± 30) on mesoporous graphitic carbon nitride (mpg-C3N4) using a magnetron sputtering cluster beam source. Electron microscopy characterization confirms that the PtN catalysts exhibit uniform size and excellent dispersion. X-ray photoelectron spectroscopy (XPS) measurements reveal no significant ionic signals, suggesting a low oxidation state of the catalysts. Pt2 and Pt3 demonstrate superior activity in the hydrogenation of styrene. Our work holds significant potential for advancing the production of high-performance catalysts.
期刊介绍：
Catalysis Letters aim is the rapid publication of outstanding and high-impact original research articles in catalysis. The scope of the journal covers a broad range of topics in all fields of both applied and theoretical catalysis, including heterogeneous, homogeneous and biocatalysis.
The high-quality original research articles published in Catalysis Letters are subject to rigorous peer review. Accepted papers are published online first and subsequently in print issues. All contributions must include a graphical abstract. Manuscripts should be written in English and the responsibility lies with the authors to ensure that they are grammatically and linguistically correct. Authors for whom English is not the working language are encouraged to consider using a professional language-editing service before submitting their manuscripts.
