NOVELTY - The method involves dispersing noble metal salt and a carbon carrier into water, and heating to evaporate a solvent to dryness so that the noble metal salt is adsorbed on the carbon carrier to obtain a solid powder precursor. The obtained solid powder precursor is heated in a reducing atmosphere to reduce noble metal salt to obtain a noble metal simple substance and obtain an intermediate product. The obtained intermediate product is reacted with the gas obtained after the elemental chalcogen nonmetal sublimes in a reducing atmosphere, or the obtained intermediate product is directly placed in an oxygen-containing atmosphere for reaction at the temperature of 250-450 ℃ to obtain the carbon-supported noble metal compound. The noble metal element in the solid powder precursor is present in an amount of 5 to 40% by mass. USE - Method for preparing supported noble metal compound for cathodic oxygen reduction catalyst in process of preparing hydrogen peroxide by oxygen reduction (all claimed). Can also be used for chemical synthesis, pulp bleaching, environmental treatment and hydrogen peroxide fuel cells. ADVANTAGE - The method prepares the supported noble metal compound catalyst by simple low temperature method, improves the oxygen reduction reaction synthesis of hydrogen peroxide selectivity and activity, mild reaction condition, simple operation, and suitable for large-scale production. DESCRIPTION OF DRAWING(S) - The drawing shows a graphical representation of stability curve of the electrosynthesis hydrogen peroxide of the carbon-loaded platinum diselenide.
