Sheng, Yao Wang, Xueguang Xing, Zhikang Chen, Xiubin Zou, Xiujing Lu, Xionggang Highly Active and Chemoselective Reduction of Halogenated Nitroarenes Catalyzed by Ordered Mesoporous Carbon Supported Platinum Nanoparticles Highly dispersed Pt nanoparticles (∼2.2 nm) on ordered mesoporous carbon (Pt/CMK-3–HQ) were first prepared through a two-step impregnation route with aqueous solutions of 8-hydroxyquinoline (8-HQ) and H<sub>2</sub>PtCl<sub>6</sub>, respectively. The Pt/CMK-3–HQ quantitatively converted various halogenated nitroarenes to the corresponding haloanilines using hydrazine hydrate with unprecedented activities (e.g., turnover frequency for <i>o</i>-chloronitrobenzene was 30.2 s<sup>–1</sup>) and exhibited high stability with 20 cycles without decrease in catalytic efficiency. The high activity and chemoselectivity of Pt/CMK-3–HQ were attributed to the cooperation effect between Pt and N species, promoting cleavage of hydrazine to generate more Pt–H<sup>–</sup> and N–H<sup>+</sup> species for reduction of nitro groups and weakening the interaction between halogen groups and Pt atoms for activation of C-halogen bonds.
