Co$_3$O$_4$ nanocubes; Rhodamine B; photocatalysis; degradation.

Monodispersed Co$_3$O$_4$ nanocubes were prepared by a simple hydrothermal route with sodium pentanesulphonate,employing Co(NO$_3$)$_2$·6H$_2$O and NH$_3$·H$_2$O (28 wt%) as the starting reactants.The final product was characterizedby powder X-ray diffraction, energy-dispersive X-ray spectrometry, scanning electron microscopy and transmission electronmicroscopy. The as-prepared Co3O4 nanocubes could photocatalytically degrade organic dye Rhodamine B under irradiation of 365 nm ultraviolet light.
