Abstract

VOCs are a group of compounds that have negative impacts on the environment and humans. VOCs can be treated by many methods, notably the catalytic oxidation method. In this study, the synthetic catalysts were MnCoCe oxide and NiCo oxide supported on cordierite. The typical analytical methods used include SEM EDX, XRD, N₂ adsorption-desorption isotherms, TPD-O₂, and TPR-H₂. GC and GC-MS were used to analyze the gas composition. The catalyst has high activity at temperatures above 300 ^oC. MnCoCe oxide/cordierite completely converts toluene with 100% selectivity to CO₂ at 350 ^oC. NiCo oxide/cordierite has lower activity, converting 80% toluene with 100% CO₂ selectivity.
