Abstract
The invention relates to a method of producing hydrogen peroxide by direct reaction between hydrogen and oxygen in an aqueous reaction medium, in which method hydrogen and oxygen are contacted with a catalyst suspended into the reaction medium, and the catalyst is a catalytically active surface material deposited on a support of porous silica, alumina or non-fluorinated carbon having a BET surface less than about 150 m.sup.2 /g, wherein pores with a diameter exceeding about 10 nm constitute more than about 50% of the total pore volume. The invention also relates to a catalyst useful in the claimed method.
