原始语种摘要: Abstract(#br)Microperoxidase‐8, a small, peroxidase‐type enzyme was immobilized into nanoparticles of the mesoporous and ultra‐stable metal–organic framework (MOF) MIL‐101(Cr). The immobilized enzyme fully retained its catalytic activity and exhibited enhanced resistance to acidic conditions. The biocatalyst was reusable and showed a long‐term stability. By exploiting the properties of the MOF′s framework, we demonstrated, for the first time, that the MOF matrix could act in synergy with the enzyme (Microperoxidase‐8) and enhance selectivity the oxidation reaction of dyes. The oxidation rate of the harmful negatively charged dye (methyl orange) was significantly increased after enzyme immobilization, probably as a result of the pre‐concentration of the methyl orange reactant owing to a...
