Iron(III)protoporphyrin/MCM41 catalyst as a peroxidase enzyme model: Preparation and typical test reactions

MCM41 was synthesized and Fe(III)protoporphyrin(IX) (Fe(III)PPIX) was directly encapsulated into MCM41 pores through the self-assembly formation mechanism. Fe(III)PPIX/MCM41 was used in some typical and industrially important reactions. Kinetic parameters including rate constants, turnover number, Michaelis constant and catalytic efficiency were obtained. Results showed that Fe(III)PPIX/MCM41 catalyst is able to mimic horseradish peroxidase.
