Abstract
NiO/LaCrO3 catalyst was prepared using citric acid method from its’ precursor of nitrates. The preparation steps consist of wet impregnation of varied percentages (b/b) NiO into LaCrO3 , evaporation and calcination. To examine its activity, the catalyst was used in CH4 conversion experiment at different temperatures. The experimental results indicated the dependency of CH4 conversion on temperature, with the highest methanol formation (176.05 mL) was achieved at 100 oC under Ar/CH4 (40/10, 50 mL min-1) as a feed. Adding O2 gas into feed increasing the methanol formation and the increment achieved 68%. X-ray diffraction examination proved that its crystalline phases consist of NiO cubic structure in a bulk crystalline of LaCrO3 perovskite structure. Furthermore, increasing Ni content enlarging unit cell volume of catalyst. FTIR analysis appeared to indicate that both the Lewis and Brønsted-Lowry acid sites were involved in the catalytic conversion of CH4.
