CATALYST COMPRISING NANOPARTICLES IMMOBILIZED ON THE SUPPORT SURROUNDED BY POLYELECTROLYTE LAYERS

摘要

The present invention relates to a catalyst having surface-modified metal nanoparticles immobilized in a stationary phase in which a polymer electrolyte membrane is formed, and a preparation method thereof. The catalyst of the present invention may be used in a process for producing hydrogen peroxide by direct synthesis from oxygen and hydrogen.
