Abstract

The electrodeposition has been widely studied due to the demonstration that the magnetic field can be used to change the electrodeposition, controlling the morphology of electrodeposited films or mass transport of reactants towards the electrodes and also the rate of reaction in the electrode / electrolyte interface. The term magnetoelectrolysis refers to the different ways in which the magnetic field influences an electrochemical process. As we recently demonstrated that time domain nuclear magnetic resonance (TD-NMR) can be an important analytical tool for the study of electrodeposition of paramagnetic ions in solution, we intend to use it to study the magnetic electrolysis phenomenon in situ, using the NMR magnet to induce magnetic convections. For this it will necessary : the construction of electrochemical cells for in situ analysis with TD-NMR; studies of in situ electrodeposition reactions of paramagnetic ions, Cu 2 +, Ni +2, Cr 3 +, Mn +2; studies of the effect of magnetic fields parallel and perpendicular to the working electrode in electrodeposition reaction of paramagnetic ions, the study of electrodeposition reaction in the presence of a magnetic field gradient of unilateral NMR spectrometer and the theoretical / experimental study of magneto-convective forces in electrochemical experiments / TD-NMR.
