Dual role of Cu 2 O nanocubes as templates and networking catalysts for hollow and microporous Fe-porphyrin networks

Cu O nanocubes were used for the synthesis of hollow and microporous Fe porphyrin networks (H-MFePN). In this synthesis, Cu O nanocubes performed not only as networking catalysts but also as shape controlling templates. MFePN were formed on the surface of the Cu O 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.
