Abstract
Abstract The disclosed electrode includes an electroconductive substrate and an electron-transfer catalyst immobilized on the conductive support surface by being covalently bonded thereto via a linking ligand. The link (ligand) used to covalently bond the catalyst to the support surface can be either electrically conductive or non-conductive.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
65 words
In an electrochemical cell, the improvement comprising an electrode comprising an electroconductive carbon substrate, a ligand covalently bonded to said substrate, said ligand being selected from the group consisting of haloacyl and halomethyl, and an electron-transfer catalyst linked to said substrate by covalent bonding to said ligand, said electron-transfer catalyst serving to enhance electron transfer between said substrate and a molecule to be acted upon.
Claim 2
Dependent Claim
65 words

Claim 3
Dependent Claim
13 words
The electrode of claim 1 wherein said electron-transfer catalyst is a redox catalyst.
Claim 4
Dependent Claim
16 words
The electrode of claim 1 wherein said ligand is a bromoacyl group or a chloromethyl group.
