4. Conclusions
Thermocatalytic degradation of MB, considering a variety of factors,
such as reaction temperature, reaction time, catalyst dosage,
initial concentration and initial pH of the solution, has been
explored under room-temperature excitation. In the past, it was
originally viewed as impossibility [30], while it ultimately exhibited
that the degradation occurred could be conducted. At optimum
condition, the abatement rate, containing adsorption and thermocatalytic
degradation processes, can reach the highest level
of 82.07% solely response to temperature in darkness. Based on
experimental results, the dependence of degradation rate on reactional
time was modeled considering that it was found similarly to
Langmuir–Hinshelwood behavior, and the reactional mechanism
for thermocatalytic degradation was assumed and proposed elaborately.
Moreover, the content of MB adsorbed onto catalyst was
discovered to be crucial in degradation performance. We expect
that this degradable route will be extendable to deal with more
deleterious pollutants from industrial wastewater and provide a
practical guidance on environmental treatment domain.
