Photo-electrochemical properties of hydrogen in anodically oxidized niobium

Photoelectrochemical study of hydrogen in oxide films of Zr based alloys for fuel cladding materials of light water reactors

“…The detailed description of the Mott-Schottky analysis has been previously reported in the literature [12,13]. As seen from Fig.…”

Comparative study and imaging by PhotoElectroChemical techniques of oxide films thermally grown on zirconium and Zircaloy-4

“…In the present study, we are mainly interested in understanding how alloying elements, such as iron and chromium, oxidize during the formation of thermal oxide scales on Zircaloy-4. For this purpose we used the PhotoElectroChemical technique (PEC) which is known to be a valuable tool for investigating semi conducting materials in terms of electro-optical properties, more or less directly related to the chemical composition and structure of the material [4][5][6][7][8][9].…”

Fabrication of Porous Nb[sub 2]O[sub 5] by Plasma Electrolysis Anodization and Electrochemical Characterization of the Oxide

“…[14][15][16] The oxide has rectifying properties, i.e., the current flows in the cathodic direction but not in the anodic direction. 17 Nb oxides are found in a large variety of applications, such as oxygen and biosensors, 18,19 electrochromic material, [20][21][22] catalysis, 23 and capacitors. [24][25][26] So-called valve metals ͑film forming metals͒ in electrolyte form a porous oxide when subjected to high anodic potentials ͑over dielectric breakdown͒.…”
