Abstract
The present invention relates to a novel alloy catalyst material for use in the synthesis of hydrogen peroxide from oxygen and hydrogen, or from oxygen and water. The present invention also relates to a cathode and an electrochemical cell comprising the novel catalyst material, and the process use of the novel catalyst material for synthesising hydrogen peroxide from oxygen and hydrogen, or from oxygen and water.
Claims14
A process for the electrochemical synthesis of hydrogen peroxide from an electrolyte comprising water wherein an alloy catalyst material catalyses the oxygen reduction reaction,
- wherein the alloy catalyst material comprises an active metal for catalysing the oxygen reduction, and a less active metal for preserving the O—O bond,
- wherein the active metal is selected from the group consisting of copper (Cu), ruthenium (Ru), rhodium (Rh), palladium (Pd), and platinum (Pt), and any combinations thereof, and
- wherein the less active metal is selected from the group consisting of gold (Au) and mercury (Hg), and any combinations thereof,
- with the proviso that said alloy catalyst material cannot be an alloy made of gold and palladium.
