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 o-chloronitrobenzene was 30.2 s–1) 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 and N–H+ species for reduction of nitro groups and weakening the interaction between halogen groups and Pt atoms for activation of C-halogen bonds. %I ACS Publications
