Although photocatalysis has been actively surveyed on removing organic pollutants in ultraviolet (UV)
environment, because of lacking UV in solar exposure, photodegradation is difficult to be considerably
degraded in conventional exposure condition. In this work, an innovative approach was proposed to
compensate for it, which was developed in model wastewater using thermal sensitizer at room temperature.
At the optimal component condition, the removal rate of adsorption and thermocatalytic
degradation processes can reach the highest level of 82.07% solely response to temperature in the
dark. Moreover, the kinetics of degradation rate was modeled considering that it was found similarly
to Langmuir–Hinshelwood behavior, and a tentative mechanism was objectively established, describing
reasonably well in line with the experimental results. On the other hand, it was found that high
amount of methylene blue (MB) adsorbed onto thermal sensitizer was of unambiguous importance to
subsequent thermocatalytic performance. Briefly, all above suggest that the feasibility to the thermodegradation
route has been successfully verified under room temperature excitation. Herein the insight
into degradation pattern of dye over thermal excitation may further enlarge applications for wastewater
treatment.
