In this study

electrodeposition and thermal decomposition were alternatively used for the fabrication of a series of novel multilayer-structured SnO

-Sb-Ce/Ti (SSCT) electrodes

and their physiochemical and electrochemical properties were investigated for electrochemical oxidation of tetracycline (TC) in aqueous medium. Experimentally

after the SnO

2

-Sb-Ce (SSC) composite was electrodeposited for 120 s on the titanium substrate in aqueous solution

the outer thermal coatings composed of SSC were synthesized by a hydrothermal method. Both influences of electrodeposition time (T

ed

) and thermal decomposition time (T

td

) were investigated to obtain the optimum preparation. It was found that when increasing T

ed

to a certain extent a longer lifetime of electrode can be achieved

which was attributed to a more solid interlayer structure. A notable SSCT
