ABSTRACT:
A method for producing a high concentration of hydrogen peroxide by reacting oxygen and hydrogen directly in a neutral reaction medium that contains a promoter comprising a halogen containing compound, which halogen containing compound contains at least one halogen other than fluorine, at a reaction temperature in the range of from 0.degree. to 50.degree. C. and at a reaction pressure in the range of from 3 to 150 kg/cm.sup.2 .multidot.G in the presence of a platinum group metal catalyst supported on a catalyst carrier containing a heteropolyacid that has been made insoluble in water or a platinum group metal catalyst supported on a catalyst carrier comprising activated carbon that is supporting a heteropolyacid.
