BIMETALLIC ELECTROCATALYST FOR USE IN MOLECULAR ELECTROSYNTHESIS AND PREPARATION METHOD THEREFOR

摘要

The invention relates to the mining industry and to an electrocatalyst for producing an oxidising agent by means of the partial oxidation of sulphurous compounds, such as formamidine disulphide (FDS) from thiourea (Tu). The inventive material and process are advantageous over the prior art in that they enable efficient partial oxidation of sulphurous compounds without producing any parasitic reactions such as subsequent oxidations or oxygen evolution. The structure of the invention consists of a bimetallic electrocatalyst having a molar ratio of between (0.8 - 1) Pt : (0.012- 0.016) Pb on the surface of the support and the method for preparing same comprises the use of the sol-gel technique using a polymer precursor.
