The effect of calcium on the properties of molybdenum nitride film electrode was studied by using XRD, SEM and cyclic voltammetry. The results show that the specific electric capacity and the voltage operating range of electrode vary with the concentration of additive in the dipping solution. At the optimum concentration of additive in the dipping solution, the specific electric capacity of the electrode is 2.1 times as large as that of the electrode prepared in the dipping solution without additive, and the voltage operating range of electrode is increased by 0.11 V. The active mechanism of calcium on the properties …

Desized polyacrylonitrile (PAN) based carbon fibers (CF) were chemically and electrochemically oxidized and reduced. CF surfaces were activated via cyclic voltammetry studies with anodic and cathodic scans. The changes in CF surfaces were studied by contact angle measurements. Lifshitz-van der Waals and acid-base components of single fibers were determined. In general, oxidation resulted in the formation of an acidic surface energy component and reduction gave rise to no change in the number of basic functionalities at the CF surface.
