Co3O4 was synthesized by hydrothermal method followed by calcination and the Co3O4/bisulfite system was investigated to degrade MB to determine the chemo-catalytic property of Co3O4. A removal rate of 93.9% was achieved in 2h with this system and the excellent stability and recyclability of Co3O4 was confirmed by recycling tests. The possible mechanism of chemo-catalytic degradation of dyes by Co3O4 was proposed.
