heatsensitive catalyst was prepared by a high temperature solid phase method. The product was characterized by X-ray diffraction (XRD)

transmission electron microscope (TEM)

thermogravimetric analysis (TGA)

UV-Vis spectroscopy (UV-vis)

and scanning electron microscopy (SEM). The thermocatalytic degradation behavior for methylene blue (MB) was investigated at near room temperature. The results showed that

when the system temperature was increased from 30

35

to 40 ℃ at the initial concentrations of 30

40

and 50 mg/L

their corresponding removal rates reached 68.35%

79.64% and 88.89%

respectively. The optimal degradation rate was achieved in the conditions of the treatment time of 48 h

the initial concentration of MB at 30 mg/L

the dosage of 45 mg for thermal catalyst

and at 40 ℃ in dark. Besides

the degradation products were analyzed by gas chromatographymass spectrometer (GCMS). The result indicated that the main products were dichloromethane and toluene

confirming the true occurrences of the degradation for MB. In conclusion

the thermocatalytic degradation route under near room temperature may provide a potential method in the treatment for waste water in industry.
