SYNTHESIS OF URANIUM OXIDE NANOCLUSTERS ON THE SURFACE OF OXIDIZED ALUMINUM
Abstract
Deposition of the products from photocondensation of acetone and uranium on the surface of oxidized aluminum with the use of hydrogen peroxide has been studied by the methods of electronic and IR absorption. It has been demonstrated that in the process of deposition the sexavalent uranium peroxide nanoclusters, strongly bonded to the substrate, are formed. Heating of the substrate and of the deposited uranium peroxide to 400-450°C offers the production of the β-UO3 – type uranium oxide and to 500-600°C – of different forms of U3O8.
