Do you want to say that copper catalyzes the decomposition of organic peroxides into oxygen and the original organic compound?
Not exactly but close. I think the reason why it's not widely known is because it was a patented monopoly. The patent says "If the ether contains
peroxides, the action of copper results in the formation of a small amount of organic acids" and magnesium hydroxide is recommended for removing these
to apparently give pure ether. Much ether was packaged under this patent by Squibb. Alumina is a one step substitute nowadays.
