Electrochemical fabrication of electroactive ordered mesoporous electrode.
A novel and simple method for the electrochemical modification of ordered mesoporous silica is described. A well-organized thin film of amine-functionalized ordered mesoporous silica has been deposited electrochemically on the electrode surface. The resulting amine-functionalized electrodes were then subjected to post-functionalization with catechol moieties through electrochemical generation of reactive o-quinone followed by covalent bonding to the anchored amine groups inside the mesoporous channels of silica to afford the corresponding modified electrodes bearing aminocatechol electroactive groups. This simply obtained nanoporous modified electrode with adequate loading of electroactive groups shows very good electrochemical responses.
