Toluene Oxidation using K-OMS 2 Synthesized Via Hydrothermal Process by Central Composite Design

Synthesis methods for K-OMS 2 mostly involve calcination process. This study showed a simple method of producing K-OMS 2 via uncalcined route. Sensitivity analysis (CCD) was used to study the effects of hydrothermal time and temperature on toluene oxidation using K-OMS 2 catalysts. Catalytic activit...
