ABSTRACT Appropriate deposition of metal complex‐based catalysts on solid carriers sometimes results in considerably higher catalytic activity than that of the metal complex alone, due to interactions between the complex and the solid. These catalysts could be a part of single‐molecule catalysts (SMCs) or site‐isolated molecular complex catalysts (SIMCs). Herein, we report a solid‐supported metal complex catalyst for CH 4 oxidation at room temperature. Specifically, μ‐nitrido‐bridged iron phthalocyanine dimer deposited on conductive carbon black can oxidatively activate the chemically stable C─H bond of CH 4 with high efficiency even at 25°C in an aqueous solution containing H 2 O 2 as an oxidant. Its catalytic activity for CH 4 oxidation is much higher than that of the commonly used Fenton reaction with Fe 2+ and H 2 O 2 under the same conditions. Such high catalytic oxidizing activity is attributable to the interaction between the specific surface sites of carbon black and the high‐valent iron‐oxo species of the catalyst molecule.
