Methods for producing by electrochemical reduction a carbon-containing material with its surface modified by organic groups, in particular functionalized organic groups. Certain embodiments of the methods include contacting the carbon-containing material with an organic diazonium salt in solvent, optionally in the presence of an electrolyte and negatively polarizing the carbon-containing material relative to an anode also in contact with an electrolytic solution separate from said diazonium salt solution, wherein the electrochemical reduction is carried out on an organic diazonium salt in protic solvent in an acid medium. Carbon-containing materials with a surface modified by organic groups and the use of these modified materials, for example for producing composite materials or for fixing molecules of biological interest, are taught.
通过电化学还原生产表面被有机基团,特别是官能化有机基团修饰的含碳材料的方法。该方法的某些实施方案包括:将含碳材料与溶剂中的有机重氮盐接触,可选择在有电解质存在的情况下进行,并使含碳材料相对于与所述重氮盐溶液分开的电解溶液接触的阳极负极化,其中电化学还原是在酸介质的质子溶剂中对有机重氮盐进行的。本发明教导了表面经有机基团修饰的含碳材料以及这些修饰材料的用途,例如用于生产复合材料或固定生物分子。
