Notes:
In this study we report on the preparation and characterization of boron nitride supportednoble metal catalysts with potential applications as catalysts for oxidation reactions. The depositionand the dispersion of the active phase were strongly influenced by the preparation process and inparticular by the solvent used as the dispersing phase. Techniques such as BET, XRD and TEMwere used to study the role played by the phase used as solvent (benzene, glyme, water, THF,diglyme, isopropanol, glycol) in particles size and dispersion of metals deposed on the BN support.Different palladium depositions under various conditions and different noble metal coatings underthe same deposition condition are presented. The catalytic performances were tested in methanetraces oxidation in excess oxygen and in the presence of water. The light-off temperature (50 %methane conversion) increased in the following order: Ag/BN 〈 Pt/BN 〈 Au/BN 〈 Pd /BN
