Abstract
Abstract: Fe x Co1−x MoO4 compounds prepared by coprecipitation were studied by XRD, electrical conductivity and mainly by absorption and emission Mössbauer spectroscopy. FeMoO4 and CoMoO4 samples were shown to contain Fe3+ and Co3+, respectively, in solid solution. Three kinds of Fe x Co1−x MoO4 solids can be described. Forx⩽0.16: one has a Β-Co(Fe2+, Fe3+)MoO4 solid solution. For 0.17⩽x⩽0.25: one has the same solid solution with its surface rich in Fe3+. Forx⩾0.26: one has the same solid solution with only bulk Fe3+, and ferric molybdate. Studies of reduction by hydrogen and of catalytic reaction of mechanical mixtures of CoMoO4 and ferric molybdate support these statements.
