Process for the electrochemical production of a carbon-containing material whose surface is modified with organic groups, and use of the modified material

摘要

A method for producing by electrochemical reduction a carbon-containing material with its surface modified by organic groups, in particular functionalized organic groups, contacting the carbon-containing material with an organic diazonium salt in solvent, optionally in the presence of an electrolyte; negative polarisation of the carbon-containing material relative to an anode also in contact with an electrolyte solution separate from the diazonium salt solution. The electrochemical reduction is carried out on an organic diazonium salt in protic solvent in an acid medium.
