Outline of Final Research Achievements

Electrochemically formed hydrogen nanobubbles were detected by re-oxidation charge at Pt(111), polycrystalline platinum and platinized platinum electrodes. In spite that the surface structures between the atomically flat Pt(111) and fractal surface of the platinized platinum electrodes were ultimately different, the surface densities of the hydrogen nanobubbles were almost identical. However, at the polycrystalline platinum, the density increased as the increase in the number of steps accomplished by surface roughening. The hydrogen nanobubbles were proved to exist at platinum and sulfuric acid aqueous solution without any artifact, such as hydrophobic contaminant. Although the electrochemical reaction of NHE proceeds heterogeneously on the three phases boundary around the hydrogen nanobubbles, the identical density of the bubble at Pt(111) and the fractal surface supported the validity of the IUPAC recommendation for the preparation of NHE to use the platinzed platinum electrode.
