AbstractAn important cause of deactivation of alumina supported transition metal (oxide) catalysts is a solid state reaction between the active component and the support. We therefore studied the hightemperature behavior of Me layers (Me = Co, Ni, Cu and Fe) on polycrystalline α-A12O3 and γ- Al2O3 substrates. The samples were first oxidized at moderate temperatures and then annealed at high temperatures (up to 1000 °C) in O2, N2, or N2/O2 mixtures. The interfacial reaction to MeA12O4 was assessed using Rutherford Backscattering Spectrometry and X-ray diffraction. The reaction rate strongly depends on the transition metal element Me: Fe < Ni < Co < Cu. Low oxygen pressures favour spinel formation. γ-A12O3 shows a much higher reactivity towards the MeOx overlayers than α-Al2O3.

Abstract We live on a planet bathed in dioxygen. Iron, the most abundant transition metal element on Earth, reacts with dioxygen to form rust and red clays. It is also an essential component of enzymes that generate the energy we need to live, but alas, many of these reactions can be harmful, leading eventually to destruction of vital organs in our bodies. We can’t live without iron and dioxygen, but there are challenges living with them!
