Electrochemical detection of peroxide-containing compounds
First Claim
1. A sensing electrode comprising a carbon electrode and a functional moiety being in association with at least a portion of a surface of said electrode, said functional moiety comprising at least one metal species that promotes decomposition of hydrogen peroxide, wherein said functional moiety comprises an organic salt of said metal which comprises metal ions and organic anions and particles of said metal, wherein a mol ratio of said metal ions and said particles of said metal ranges from 70:
- 30 to 30;
70, and wherein said metal is silver.
