Graphite is a typical electrocatalyst support in alkaline energy conversion and storage devices such as fuel cells, supercapacitores and lithium ion batteries. The electrochemical behaviour of a graphite electrode in 0.5 M NaOH was studied to elucidate its surface structure/electrochemical activity relationship. Graphite voltammograms are characterized by an anodic shoulder AI and a cathodic peak CI in addition to the oxygen reduction reaction plateaus, PI and PII. AI and CI were attributed to oxidation and reduction of some graphite surface function groups, respectively. Rotating ring disk electrode (RRDE) study revealed two different oxygen types assigned as inner and outer oxygen. The inner oxygen was reduced via the more efficient 4-electron pathway. The outer oxygen reduction proceeded with a lower efficient 2-electron pathway. The calculated percentages of the 4-electron pathway were ranged from 70% to 90%. A full mechanism for the graphite surface function groups changes over the studied potential window was suggested through the combination between the voltammetric, FT-IR and Raman results.

“…The conversion of this compound into species of higher economic value, e.g., by oxidation, is currently being actively investigated [1]. Electrochemical oxidation of alcohols is an attractive alternative to chemical oxidation [2] and ongoing research of the electrocatalytic oxidation of glycerol focuses mainly on efficiency and selectivity of the reactions.…”

Analysis by capillary electrophoresis (CE) of nanoliter samples taken 0.05 mm away from the electrode/solution interface assisted in the evaluation of glycerol electrooxidation on noble metals (Pt, Au and Pd). The fully automated all electrochemical flow system generates a conductometric electropherogram every few minutes, while exploring experimental parameters. Products like glycerate, glycolate, formate and hydroxymalonate were observed in different ratios by changing the electrocatalyst and the applied potential. On Pd, dissolved oxygen oxidizes glycerol at zero current. This new approach holds promise for fast in situ study of reaction products of heterogeneous catalysis reactions and electrode processes in general.
