Abstract

Disclosed herein is a method of preparing a catalyst having Pt—Pd dispersed in polymer electrolyte multilayers, suitable for use in production of hydrogen peroxide, wherein the use of the catalyst prepared by forming polymer electrolyte multilayers on an anionic resin support and performing sulfuric acid treatment and loading (insertion or attachment) of Pt—Pd particles can result in high hydrogen conversion, hydrogen selectivity and hydrogen peroxide yield for a long period of time.
