In this work, hexaaluminate based catalysts - namely LaMnAl11O19 andPd/LaMnAl11O19 were tested for catalytic oxidation of a model gas comprising of a mixture of CO and CH4. The co-precipitation route was employed to synthesize both catalyst sample sowing to better chances of attaining higher surface areas at higher calcination temperatures. The N adsorption isotherms yielded surface areas of 20 and 14 2 m2/g for LaMnAl11O19 and Pd/LaMnAl11O19 respectively. TheT90of CO (temperature at 90% conversion) were recorded at 482 °C and 185 °C for LaMnAl11O19 and Pd/LaMnAl11O19 respectively. Moreover, a methane conversion of 62 % at 700 °C was achieved over Pd/LaMnAl11O19 in comparison to only 28 % in case of LaMnAl11O19. The structural characterisation showed that a better mobility of oxygen atoms in the lattice structure of Pd/LaMnAl11O19 along with a more pronounced mass transport phenomenon yielded a better conversion of CO and CH4 at relatively low temperatures.
