Abstract
A process for producing hydrogen peroxide, comprising the step of producing hydrogen peroxide catalytically from hydrogen and oxygen in a reaction medium, wherein a platinum-group metal catalyst is used which comprises a platinum-group metal and, supported thereon, a niobium oxide, a mixed oxide of niobium, a tantalum oxide, a mixed oxide of tantalum, a molybdenum oxide or a tungsten oxide.
Claims5
A process for producing hydrogen peroxide comprising the step of:
- producing hydrogen peroxide catalytically from hydrogen and oxygen in a reaction medium in the presence of a platinum-group metal catalyst supported on an oxide carrier selected from the group consisting of a niobium oxide and a tantalum oxide, wherein the niobium oxide and tantalum oxide are prepared by heat treating niobic acid and tantalic acid, respectively, at a temperature of from 300.degree. to 700.degree. C.
