| Research Abstract |
It was synthesized copper-and nickel trifluoromethanesulphonate. The solubilities of these salts in organic solvents and the electric conductivities were high. The bright and smooth copper- and nickel electrodeposits were obtained from the CH_3OH baths containing these salts. The electrodeposition of metals from these baths was not easier than that from the baths containing metal trifluoroacetate. In the CH_3CN, the electrodeposition occured from Cu^+, with the result that preelectrolysis was required to reduce the Cu^<2+> to Cu^+. It was found with XPS analysis that WO_3 and MoO_3 were detected on the uppermost surface of the tangsten- and molybden electrodeposits and the lower valency metallic oxides on the surface of the closed substrate of the electrodeposits obtained from the HCONH_2 baths, respectively.
