Abstract
Official abstract text for this publication.
Provided is a catalyst for synthesizing hydrogen peroxide as represented by the following Chemical Formula 1: Rh x Ag (1-x) , [Chemical Formula 1] where 0<x<1.
First claim
Opening claim text (preview).
What is claimed is: 1. A catalyst for synthesizing hydrogen peroxide, the catalyst represented by Chemical Formula 1 provided below: Rh x Ag (1-x) , (Chemical Formula 1) where 0<x<1, wherein the catalyst contains solid rhodium (Rh) at 2 to 7% in terms of a ratio of the number of Rh atoms with respect to 100% of a total number of atoms in Chemical Formula 1. 2. The catalyst according to claim 1 , wherein the catalyst is in a form of a solid solution alloy in which Rh and solid silver (Ag) are mixed together or a core-shell structure consisting of solid Rh and solid Ag. 3. A catalyst for synthesizing hydrogen peroxide, the catalyst represented by Chemical Formula 1 provided below and in a form of a composite containing Rh and Ag, wherein the Rh and the Ag are mixed together without forming a solid solution alloy and form an interface with each other: Rh x Ag (1-x) , (Chemical Formula 1) where 0<x<1, wherein the catalyst contains Rh at 2 to 35% in terms of a ratio of the number of Rh atoms with respect to 100% of a total number of atoms in Chemical Formula 1.
