This study presents a novel method for the preparation of ZnSnO/VO nanocomposites via a sonochemical aqueous route. This method is mild, convenient, cheap and efficient. The as prepared samples were characterized by XRD, SEM, EDAX, TEM, BET, FT-IR and UV-DRS spectra. DRS spectrum shows the adsorption edge of ZnSnO-VO in visible region of spectrum. The structural and morphological features of the as synthesized ZnSnO-VO nanocomposites have been observed using both scanning and transmission electron microscopy. BET surface area analysis inferred that the prepared hetero-junctions are meso-porous in nature. The photocatalytic activity of ZnSnO-VO nanocomposites for the degradation of Eosin Yellow (EY) dye under visible light was investigated in detail. 3% ZnSnO-VO nanocomposite exhibited the highest photocatalytic performance (92% of EY degradation) when compared with 2% ZnSnO-VO and 5% ZnSnO-VO. The adsorption of Eosin Yellow followed the pseudo-first order kinetic model. Simultaneously, high stability of the sample was also investigated by four successive photodegradation of EY under visible light. The relationship between photocatalytic activity and the structure of 3% ZnSnO-VO nanocomposite is discussed, and possible reaction mechanisms are also proposed. Therefore, the facile sonochemical preparation process provides some insight into the application of ZnSnO-VO nanocomposites in photocatalytic degradation of organic pollutants.
