Some properties and thermal decomposition of iron (III) oxalate supported on HZSM‐5 and HY zeolites have been studied by GC, IR, and Mössbauer spectroscopy methods. Thermal decomposition of unsupported iron (III) oxalate took place in two stages: as indicated by peak α (giving CO 2 ) and peak γ (yielding CO and CO 2 ), but for iron (III) oxalate supported on zeolites, an additional peak β (producing CO and CO 2 ) appeared as a result of the interaction between C 2 O 4 2− and Al 3+ . At 500°C Fe 2 (C 2 O 4 ) 3 ‐HZSM‐5 system produced α‐Fe in H 2 due to the weak interaction between the salt and the support. For Fe 2 (C 2 O 4 ) 3 ‐HY system in H 2 , at 500° the solid products consisted of α‐Fe and a little highly dispersed Fe (0) together with Fe (II) and F(III) oxides, which were difficult to be reduced.
