Abstract: A commercial cordierite sample showed a small catalytic activity in iso-propanol conversion carried out at 150-350 °C and no measurable activity in CO oxidation by O2. On the other hand, supporting NiO on Al2O3–modified cordierite resulted in the formation of an active solid that having good catalytic activity in iso-propanol conversion and CO oxidation by O2. These two reactions were carried out at 150-350 and 200 °C, respectively. The results revealed that the catalyst containing 5wt (percent) NiO showed the biggest activity in the alcohol conversion and acted as selective dehydration catalyst. The catalyst sample containing 20wt (percent) NiO exhibited a good activity in CO oxidation by O2 which decreased progressively by increasing its calcination temperature within 350-600 °C. Al2O3–treated cordierite dissolved a portion of NiO in its lattice which increased by increasing the calcination temperature within 350-600 °C.
