Abstract
A method for converting a supported metal nitrate into the corresponding supported metal oxide comprises heating the metal nitrate to effect its decomposition under a gas mixture that contains nitrous oxide and has an oxygen content of <5% by volume. The method provides very highly dispersed metal oxide on the support material. The metal oxide is useful as a catalyst or as a catalyst precursor.

A method for converting a supported metal nitrate into the corresponding supported metal oxide comprising heating the metal nitrate to effect its decomposition under a gas mixture containing nitrous oxide and having an oxygen content of <5% by volume, wherein the nitrous oxide concentration in the gas mixture is in the range 0.001 to 15% by volume, wherein the metal nitrate is impregnated onto a support material from a solution and dried to remove the solvent before heating the metal nitrate to convert it to the corresponding metal oxide.
