Elucidating the Role of Oxide-Oxide/Carbon Interfaces of CuO-CeO/C in Boosting Electrocatalytic Performance.

Herein, we report the synthesis and bifunctional oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) activities of a CuO-CeO/C electrocatalyst (EC) with rich oxide-oxide and oxide-carbon interfaces. It not only demonstrates a smaller Tafel slope (65 mV dec) and higher limiting current density (-5.03 mA cm) but also exhibits an onset potential (-0.

Uranium oxide catalysts: environmental applications for treatment of chlorinated organic waste from nuclear industry.

Huge amounts of nuclear waste, including depleted uranium, significantly contribute to the adverse environmental situation throughout the world. An approach to the effective use of uranium oxides in catalysts for the deep oxidation of chlorine-containing hydrocarbons is suggested. Investigation of the catalytic activity of the synthesized supported uranium oxide catalysts doped with Cr, Mn and Co transition metals in the chlorobenzene oxidation showed that these catalysts are comparable with conventional commercial ones.
