Abstract
La-Mo oxides were synthesised by heating the powder, obtained from the reaction of lanthanum nitrate with molybdenum carbonyl in organic med ia, at 573 K for 2 h. The structure, morphology and chemical compositi on were determined by oxygen determination, atomic absorption spectrom etry, X-ray diffraction and scanning electron microscopy. The results showed an amorphous structure. After heating the compound in vacuum, w e obtained the X-ray diffraction pattern of La-2(MoO4)(3). The electro chemical behaviour of the La-Mo oxides was determined in KOH 0.5 M. In the range 700-1000 mV vs Hg/HgO/KOH 0.5 M electrode, the results show ed a very good performance for the oxygen evolution reaction. (C) 1998 International Association for Hydrogen Energy.
