Dual role of Cu2O nanocubes as templates and networking catalysts for hollow and microporous Fe-porphyrin networks

Abstract

Cu₂O nanocubes were used for the synthesis of hollow and microporous Fe porphyrin networks (H–MFePN). In this synthesis, Cu₂O nanocubes performed not only as networking catalysts but also as shape controlling templates. MFePN were formed on the surface of the Cu₂O nanocubes through azide–alkyne cycloaddition of tetrakis(4-ethynylphenyl) Fe-porphyrin with 1,4-diazidobenzene. H–MFePN showed excellent catalytic activities in carbene insertion into N–H bonds, maintaining their activities during five recycle tests.
