Nanostructured Fe2O3/TiO2 thick films
(Programme and Book of Abstracts of The Second Conference of The Serbian Ceramic Society, 2013)
Thick films of nanostructured pure TiO2, -Fe2O3, Fe2O3/TiO2 (ratio 2:3 and 3:2) and a hetero-junction in the form of a TiO2 layer over a Fe2O3 layer have been fabricated by screen printing technology on a glass substrate. ...
Photocatalytic properties of hydro-and solvothermaly prepared nanosized ZnO
(Institute for Multidisciplinary Research, University of Belgrade, 2013)
Two salts of Zn were used as starting materials: Zn(CH3COO)2·2H2O for
solvothermal and Zn(NO3)2·6H2O for hydrothermal treatment. Initially,
Zn(CH3COO)2·2H2O was dissolved in ethylene-glycol in the presence of PVP ...
