The objective of this study was to optimize synthesis conditions for the Cu-K-OMS-2 hydrothermal process. The effects of ageing temperature, ageing time and amount of copper (Cu) dopant were considered via using the Box-Behnken design (BBD) method to characterize the conditions for gaseous toluene degradation. In the models studied, the independent variables were ageing temperature (55-145ºC), ageing time (6-18 h) and amount of Cu dopant (2-6% mole). The quadratic model fitted very well with the experimental data (15 runs), which showed a higher value of R2 (0.98) and adjusted R2 (0.95), confirming that the model can explain the results successfully. Ageing temperature was found to be the only significant variable for the Cu-K-OMS-2 transformation phase, with CuO and the bixbyite phase appearing as the highest ageing temperature condition. Furthermore, the effects of ageing temperature, ageing time and amount of Cu dopant on the Cu3+/Cu2+ mole ratio were also investigated. Ageing temperature and amount of Cu dopant displayed a significant effect on both toluene removal and the Cu3+/Cu2+ mole ratio. On the other hand, ageing time was not significant for both responses. The high Cu3+/Cu2+ mole ratio led to enhancement of toluene removal. The optimized conditions for Cu-K-OMS-2 synthesis were determined as 120ºC of ageing temperature, 6 h of ageing time and 6% by mole of Cu on K-OMS-2, which removed 80% of toluene at a reaction temperature of 180ºC.

The paper made a research on synergetic effect of gaseous toluene decomposition using dielectric barrier discharge plasma and adsorption. A systematic investigation on toluene removal efficiency and ozone byproduct generation was done using different types of fillers. The mixed fillers were found to be promising as ideal fillers. In terms of toluene removal efficiency, mixed fillers of zeolite and ceramic rings was the highest, around 97%, next is zeolite, then followed by ceramic rings and no filler-packed. Among the tested fillers, mixed fillers showed the least amount of ozone generation. For practical use of mixed fillers, it’s preferable to operate at 18kV than 20 kV, avoiding forming more undesirable O3byproduct on achieving the same toluene removal effect.
