Understanding the synergistic effect of bimetallic catalysts is crucial in heterogeneous catalysis. However, constructing uniform dual-metal sites is a significant challenge. In this study, a new method for constructing Pt-1-Fe-1/ND dual-single-atom catalyst was developed using nanodiamond (ND) surface decorated with Fe-1-N-4 sites. The catalyst exhibited excellent catalytic performance in nitroarenes selective hydrogenation. The findings advance the application of dual-single-atom catalysts and provide insights into synergistic catalysis at the atomic level.
Fundamental understanding of the synergistic effect of bimetallic catalysts is of extreme significance in heterogeneous catalysis, but a great challenge lies in the precise construction of uniform dual-metal sites. Here, we develop a novel method for constructing Pt-1-Fe-1/ND dual-single-atom catalyst, by anchoring Pt single atoms on Fe-1-N-4 sites decorating a nanodiamond (ND) surface. Using this catalyst, the synergy of nitroarenes selective hydrogenation is revealed. In detail, hydrogen is activated on the Pt-1-Fe-1 dual site and the nitro group is strongly adsorbed on the Fe-1 site via a vertical configuration for subsequent hydrogenation. Such synergistic effect decreases the activation energy and results in an unprecedented catalytic performance (3.1 s(-1) turnover frequency, ca. 100 % selectivity, 24 types of substrates). Our findings advance the applications of dual-single-atom catalysts in selective hydrogenations and open up a new way to explore the nature of synergistic catalysis at the atomic level.
