Electrochemical modification of a nonwoven fibrous carbon material in sulfuric acid solution

摘要

The influence exerted by the electrode polarization of ANM nonwoven fibrous carbon material in 0.25 M sulfuric acid solution on the pore composition and size, fiber surface morphology, elemental composition of fibers, quantitative and qualitative composition of surface groups, stationary electrode potential, and electrochemical capacity was examined. These properties depend on the ratio of the cathodic and anodic constituents of the current density (measured per geometric surface area).
