COPPER OXIDE/SILICON DIOXIDE COMPOSITE

摘要

A copper oxide/silicon dioxide composite in spherical and/or spheroid form with an average particle diameter of 10 to 500 nm, containing 5 to 90% by weight silicon dioxide and 10 to 95% by weight copper oxide, wherein the composite particles are core-shell particles with amorphous silicon dioxide forming the shell and copper oxide forming the core, and wherein the copper oxide contains Cu2O, CuO or a mixture thereof.
