ABSTRACT

Modulating the electronic structure of catalysts in selective hydrogenation reactions plays a pivotal role in determining their catalytic performance. In this study, we report a facile one-pot wet-chemical reduction strategy to synthesize a MoOx-modified CuNi alloy catalyst for efficient transfer hydrogenation of nitroaromatics. The CuNi-MoOx/h-BN catalyst exhibited outstanding performance, delivering nearly 100 % conversion and 99 % selectivity to anilines under mild conditions. Moreover, the catalyst displayed remarkable reusability in cyclic tests. The hydrogenation activity arises not only from the synergistic effect of Cu-Ni dual active sites, but also from the electronic environment modulated by incorporated oxides and the substituent electronic effects of nitroaromatic substrates. This work reveals that the electronic structure matching between catalyst and substrate is pivotal in governing hydrogenation activity, providing a valuable strategy for rationally tailoring the electronic environment of active sites to enable efficient synthesis of functionalized aniline derivatives.
