Kinetics investigation of toluene oxidation on perovskite-type La1-xCexMn0.6Cu0.4O3 Nano catalysts abstract

Perovskite catalysts (La1-xCexMn0.6Cu0.4O3) were synthesized via sol-gel auto combustion method. Activities of catalysts were tested in toluene oxidation. The catalysts show high activity in the range of reaction temperature (200–300 ºC). The catalytic activity increases monotonously with the degree of substitution of La by Ce. The following order was observed for performance of catalysts: La0.7Ce0.3Cu0.4Mn0.6O3 > La0.8Ce 0.2Cu0.4Mn0.6O3> La0.9Ce0.1Cu0.4Mn0.6O3 > LaCu0.4Mn0.6O3. Kinetics calculations for all catalysts were performed. Kinetic parameters including k0, E1, k0,VOC, ΔHVOC, k0,OX and ΔHOX are estimated for two Langmuir–Hinshelwood models. Kinetic study shows that LH-OS-D mechanism is more possible than LH-DS-ND mechanism. This methodology of simulation provides easily kinetic (activation energies) and thermodynamic (heats of adsorption) parameters.
