Abstract

This communication shows that colloidal suspensions of silver carbonate behave in a way which is new in voltammetric experience. Electrochemical signals typical of nucleation processes were observed during the electro-aggregation of silver carbonate on a platinum electrode. Modified electrodes, obtained by means of electro-aggregation of silver carbonate particles, showed catalytic activity towards the electrochemical oxidation of glyphosate, avoiding in this way typical passivation processes.
