Description Modification of niobium pentoxide with different dispersity via mechanochemical, ultrasound, hydrothermal
and microwave treatments (MChT, UST, HTT, and MWT, respectively) has been studied. All types
of treatment do not change of phase composition but leads to improvement (at HTT and MWT) or, on contrary,
breaking of crystal structure (at MChT and UST) and variation of crystallite size and specific surface
area. UV-Vis measurements display increase of absorption in visible region. As a result, modified samples
show higher photocatalytic activity at degradation of rhodamine B under visible irradiation. Similarly, initial
and modified Nb2O5 samples are catalysts for mechanochtmical and sonochemical destruction of the
same dye.
