Abstract

Silica gel and glass beads were modified using the acid chloride of metal-tetrakis(4-carboxyphenyl)porphine (M-TCPP) through a peptide bond, and an anion-exchange resin was modified with M-TCPP by electrostatic interaction and physical adsorption. The carriers modified with Co³⁺-TCPP proved to accelerate the following redox reaction: NADH ⁺ O₂ carriers modified with Co-TCPP NADH⁺H₂O₂. The formation of hydrogen peroxide was confirmed by means of a colored reaction. The glass heads modified with Co³⁺-TCPP exhibited the strongest activity among the tested carriers, and were expected to be useful practically as a solid catalyst for the formation of hydrogen peroxide from NADH.
