“…The arrangement of an oxide film, in turn, changes the radiation-catalytic movement and physicochemical properties, which influence the dynamic parameters. One of them, the foremost delicate is the electro physical and optical properties of metal surfaces [14][15][16][17][18][19][20][21][22].…”

Urchin-like nanocrystalline Co 3 O 4 has been success fully prepared through a hydrothermal synthesis route via a simple and elegant route at low temperature, and was characterized by thermal analysis (TGA), X-ray diffraction (XRD), scanning electron microscopy (SEM), Raman spectroscopy, nitrogen adsorption/desorption isotherms and X-ray photoelectron spectroscopy (XPS). The light-off temperature (10% conversion) of CO oxidation on Co 3 O 4 ursin-like catalyst was at 60°C and when the temperature reaches 120°C, the CO conversion ratio reaches 100%. The high relative concentration surface-adsorbed oxygen on the Co 3 O 4 ursin-like is highly active in CO oxidation reaction due to its higher mobility than lattice oxygen. The study it has been shown that the high catalytic activity and stability for CO oxidation can be attributed to its higher mobility than lattice oxygen. In addition, the oxide defects can adsorb and activate gaseous O2 to form active oxygen species, which is beneficial to promote the CO oxidation reaction. The as-obtained results make the Co 3 O 4 nanomaterial possible candidate to be used as catalyst for CO oxidation.

The study of physicochemical properties of nano-ZrO2+3mol.%Y2O3 was determined. The X-ray diffraction spectrum of the nano-ZrO2 and system nano-ZrO2+3 mol.%Y2O3 compound was drawn by the Ritveld method and the crystal structure was determined at different temperatures (T = 373, 473, 573, 673 K) and under normal conditions. The energy of the arrangement of H2 as a result of the decay of H2O, on the surface of nano-ZrO2+3mol.%Y2O3 was considered. Impacts of adsorption and desorption preparation of ZrO2+3mol.%Y2O3 nanoparticles were considered at diverse (T = 373, 473, 573, 673 K) temperatures. The thought of H2 in warm forms at nano-ZrO2+3mol.%Y2O3 framework expanded. This tells about hydrogen era by water part in close future. Nano-ZrO2 and system nano-ZrO2+3mol.%Y2O3 with the temperature range of T = 373, 473, 573, 673 K have been studied by SEM analysis. These results are promising of hydrogen generation by water splitting in near future.

“…Zirconium combinations are broadly utilized as basic materials for central items of the dynamic zone, water-cooled atomic control plants, high temperatures, and heat and mechanical loads of the coolant and other favorable components. In recent decades, numerous multilayer coatings have been systematically examined concerning radiation-induced flaws and the accompanying changes in mechanical characteristics in irradiated materials [ 20 , 21 ]. These multi-crystal structures, in which vacancies and interstitials can recombine, are frequently employed as self-healing coverings in radiation point defects [ 6 ].…”

Seawater Splitting for Hydrogen Generation Using Zirconium and Its Niobium Alloy under Gamma Radiation

Hydrogen production is produced for future green energy. The radiation–chemical yield for seawater without a catalyst, with Zr, and with Zr1%Nb (Zr = 99% Nb = 1%) were (G(H2) = 0.81, 307.1, and 437.4 molecules/100 eV, respectively. The radiation–thermal water decomposition increased in γ-radiation of the Zr1%Nb + SW system with increasing temperature. At T = 1273 K, it prevails over radiation processes. During the radiation and heat radiation heterogeneous procedures in the Zr1% Nb + SW system, the production of surface energetic sites and secondary electrons accelerated the accumulation of molecular hydrogen and Zr1%Nb oxidation. Thermal radiation and thermal processes caused the metal phase to collect thermal surface energetic sites for water breakdown and Zr 1%Nb oxidation starting at T = 573 K.
