The highly effective g-C$_3$N$_4$ hybridized CdS photocatalysts were synthesized via a successive calcination andhydrothermal process. The as-prepared photocatalysts were characterized by X-ray powder diffraction, transmission electronmicroscopy and UV–Vis diffuse reflectance spectroscopy. The photocatalytic performance of the C$_3$N$_4$/CdS nanocomposites was evaluated by the photodegradation of RhB under visible light irradiation. The results showed that photocatalytic ability of the C$_3$N$_4$/CdS nanocomposites was higher than that of pure C$_3$N$_4$ and CdS. The enhanced photocatalytic activity could be attributed to the high separation efficiency of the photo-excited electron-hole pairs. A possible mechanism of the photocatalytic degradation of RhB on C$_3$N$_4$/CdS nanocomposites was also proposed.
