Abstract [eng] |
The dissertation focuses on a simple, sustainable and low-cost approach to design Ag-CeO2 nanoheterostructures in aqueous solutions via photochemical UV-light driven process. The proposed synthesis method comprises two steps: photochemical CeO2 synthesis using sodium azide and a photochemical synthesis of Ag-CeO2 nanoheterostructures, where previously synthesized CeO2 nanoparticles are applied as a photoactive compound. No organic solvents or additives were applied in order to obtain particles with an uncoated, thus more reactive surface expecting to further apply the as-prepared structures for photocatalysis. Moreover, since no organic solvents but ethanol are used and no toxic waste is formed during the reaction, the proposed synthesis method could be defined as a sustainable route to the formation of nanoparticles. The as-prepared Ag-CeO2 nanoheterostructures. demonstrated visible light driven photocatalytic activity on photocatalysis of TBT and are expected to find applications in environmental processes. |
