    摘要: An electrode has a graphite surface at least part of which is an edge-plane graphite surface to which Cr(III) complexes are attached by surface C--O groups. The graphite can be polished pyrolytic graphite. The complex coverage can be 5-20%. The complex may comprise proteins, enzyme substrates, specific binding agents, intermediate metabolites or the like, e.g. the protein plastocyanin, so that direct unmediated electrochemistry is possible at the electrode.
