Mossbauer spectroscopy has been proven to be a useful tool for investigating the nature of supported metal catalysts, especially when these contain Fe, a commonly encountered Mossbauer isotope [lO]. It is hoped that this can provide additional insight into the state of Fe active sites during the online or quasi in situ conditions. This chapter studies the quantitative relation between the real state of active sites and reaction condition and the possible mechanism for PROX reaction over the supported MFe catalysts by using the in situ Fe-M6ssbauer spectra investigation.
