摘要

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.
