Site Selective Generation of Sol–Gel Deposits in Layered Bimetallic Macroporous Electrode Architectures
Résumé
The elaboration of an original composite bimetallic macroporous electrode containing a site-selective sol–gel deposit is reported. Regular colloidal crystals, obtained by a modified Langmuir–Blodgett approach, are used as templates for the electrogeneration of the desired metals in the form of a well-defined layered bimetallic porous electrode. This porous matrix shows a spatially modulated electroactivity which is subsequently used as a strategy for targeted electrogeneration of a sol–gel deposit, exclusively in one predefined part of the porous electrode.
