A contracted Ni2+ coordination site distorted in the direction of Ni•••Mg and Ni•••Ni was found to be responsible for catalytic N2O decomposition when the Ni2+ is diluted in a MgO matrix (Ni2+/Mg2+ atomic ratio ~ 1.0) based on a local structure study by nickel K-edge X-ray absorption fine structure spectroscopy.
