Abstract: The direct electrochemical synthesis of metal alkoxides [Ti(OEt)4, Ti(OPr-#em/em#)4, Ti(OBu)4, Ti(OEt)2(acac), Cu(OEt)2, Cu(OBu)2, Mg(OEt)2 and Ni(OEt)2] were studied by anode dissolution of metals in absolute ethanol in the presence of a conductive additives. The anodic behaviour of Ti electrode in ethanol was investigated by using cyclic voltammetry(CV). These metal alkoxides were characterized by FTIR spectra. The results show that direct electrochemical synthesis of metal alkoxides have a high current efficiency and electrolysis yield. These alkoxides have a high purity and can be directly used as the precursor of nanosize oxides prepared by sol-gel procedure. The anodic behaviour of Ti electrode in alcohol is markedly the feature of the pitting corrosion. The passivation of Ti anode would occur in the presence of trace water.

Key words: Organic electrosynthesis, Metal alkoxides, Cyclic Voltammetry, FTIR, Sol-gel
