Comparative morpho-structural and electrochemical characterization of the La and F doped porous Ti/SnO2 dimensionally stable anodes

Abstract

In this paper are presented the morpho-structural and electrochemical characteristics of porous $Ti/SnO_{2}\text{-}{La}$ and $Ti/SnO_{2}\text{-}F$ dimensionally stable anodes obtained by “spin-coating” method. $SnO_{2}\text{-}La$ and $SnO_{2}\text{-}F$ films were prepared by sol-gel technique using ethanolic solution. Uniform deposition of the $SnO_{2}\text{-}F$ and $SnO_{2}\text{-}La$ gel onto the Ti surface with typical mud cracked-like structures were found. The results of electrochemical characterization and preliminary testing in doxorubicin degradation of both electrodes confirmed their electrocatalytic activity towards advanced electrooxidation processes.
