My. Sinev et al., STRUCTURE, REDOX PROPERTIES AND CATALYTIC BEHAVIOR OF MIXED IRON-LITHIUM MOLYBDATES, Applied catalysis. A, General, 148(1), 1996, pp. 41-50
A series of iron-lithium mixed molybdates of the general formula LixFe
1-xMoO4 (x = 0.45-0.55) was synthesized and characterized by XRD and M
ossbauer spectroscopy. The modification of this system by a Li to Fe r
atio variation at constant (Li + Fe) content gives an opportunity to s
tudy structure-activity relations in catalytic methane oxidation to fo
rmaldehyde. Other products registered by means of gas chromatography a
re ethane and carbon oxides. Reduction and oxidation of the samples wa
s also studied. The influence of stoichiometry of the mixed molybdates
on their structure, ion state in the lattice and consequently on thei
r catalytic performance was evaluated.
