According to cyclic voltammograms, a potential of −2.3 V vs. Ag/AgNO3 (0.1 M), LiClO4 (0.1 M) in acetonitrile, was chosen for running electrolysis at platinum (Pt), graphite (G) and glassy carbon (GC) electrodes. Qualitative analysis was

The scientific area that concerns this work, Electrochemenergy (EC.E), involves important contributions on this subject and there are many and varied new contributions to be made. This review presents some of these studies, some of them completed, others in progress and others to be carried out; it is important to highlight the current importance of working together with the fields of nanoscience and nanocatalysis in the scientific area.
