Mössbauer study of iron phthalocyanines as catalysts of cumene oxidation
Abstract
Mössbauer spectra of mixed Cu–Fe poly(phthalocyanine) catalysts show that the presence of copper ions in the poly(phthalocyanine) core influences the distribution of iron species and their ability to undergo oxidative destruction to iron oxides. The distribution of the two main species is dependent on the Cu/Fe ratio in the catalysts and corresponds to the catalytic activity.
