Abstract

In this paper, a series of nanoparticle bonded metalloporphyrins with different saturation magnetization were synthesized by a modified silanation method. Under geomagnetic field (5 × 10−5 T), with the increase of the saturation magnetizations, the growth rate of yields of cyclohexanol in the cyclohexane oxidation with iodosylbenzene catalyzed by these nanoparticle bonded metalloporphyrins followed the order of ironporphyrin > manganeseporphyrin > cobaltporphyrin.
