Abstract	Ultrasound energy has been successfully employed to synthesize CdSe/TiO$_{2}$ nanocatalysts for the photocatalytic degradation of phenol under solar light irradiation. The photocatalytic performance test was carried out using TiO$_{2}$ as well as synthesized CdSe/TiO$_{2}$ nanocatalysts. Nanocatalyst characterization was accomplished using XRD, SEM, FTIR, BET and UV–vis spectroscopy. It was shown that the synthesized nanocatalysts have crystal characteristics and are in nano-scale size range. The coupled nanocatalyst has shown a shift in the absorption spectrum from the UV range to the visible range. The results of photocatalytic tests showed that the CdSe/TiO$_{2}$ coupled nanocatalyst could remove phenol from wastewater under solar light irradiation, while TiO$_{2}$ did not have enough activity in this process. It is also shown that the CdSe nanoparticles act as photosensitizers, not only extending the spectral response of TiO$_{2}$ to the visible region but also reducing the electron–hole recombination. Furthermore, the CdSe/TiO$_{2}$ synthesized samples provided more photomineralization efficiency than that of TiO$_{2}$ in terms of total organic carbon analysis.
