Electrochemical oz one generation on the Ti/Sn-Sb-Ni as anode a nd improve ment of electrocatalytic pro perties vi a carbon nano tube

Electrochemical ozone production (EOP) has advan tages over the classic corona method for ozone p roduction, for examplehigh conc entrations i n the gas and liquid phases, simpl e system design and low voltage operation. In the electrochemical pro cess, ozone is generate d at the anode surface. Ho wever, oz one generation severely competes with O۲ evolution which is thermodynamicall y favorable. (seeEqs. ۱ and ۲):(...)Variou s anode ma terials have been studied for electrochemical ozone production such asplatinu m,PbO۲,Si/ TiOx/Pt/TiO x,Pt-TaOx, boron doped diamond (BDD),a ndglassy carbon.Recent reports on mixed oxide electrodes of Sn, Sb and Ni prepared by thermal decomp osition on titanium show high cu rrent efficiency, depe nding on o perating co nditions, at mod erate temperatures and anode potentials. The goal of the present work is to improve the electroc atalytic activity and efficiency of anodes for electroc hemical o zone gener ation by using C NTs as a dopant in a S n-Sb-Ni-CNT composite coating on a Ti substrate [۱-۳].
