Abstract

 

         In this work, the possibility of methylene blue electrochemical reduction, assisted by a hybrid material, based on polynaphthoquinones, doped by Ti/TiO2/VO(OH) composite, has been evaluated from the theoretical point of view. Two mathematical models, one referent to the electrode preparation and another, referent to its action with methylene blue, have been described and analyzed. It was shown that in both of the processes the steady-state stability may be easily obtained and maintained. On the other hand, the oscillatory behavior in this system is possible, being caused by the DEL capacitance influences of both chemical and electrochemical stages.
