Abstract The electro-oxidation of gold and thiourea (TU) in aqueous acid solutions is investigated by means of in situ FTIRRAS measurements complemented by voltammetry. The formation of soluble species related to the gold(I)–TU complex and TU electro-oxidation products is monitored by following the changes in the IR spectra with the applied potential in the range −0.1–1.5 V. Experimental data show that gold electrodissolution produces soluble [Au(CS(NH 2 ) 2 ) 2 ] 2 SO 4 species. The IR… CONTINUE READING
