Abstract

The myoglobin (Mb)-intercalated magadiite nano-composite (Mb-magadiite) was successfully obtained by the exfoliation-reassembly method under mild conditions and was used to catalyze the oxidation of o-phenylenediamine in organic solvents with different hydrophobicities. The results showed that the immobilized myoglobin had higher catalytic activity and stability than free Mb in organic solvents with moderate hydrophobicities. The effects of the organic solvents on the catalytic performance of the immobilized myoglobin were also discussed.
