Abstract

Fe1-xNixO3±δ catalyst was prepared using citric acid method fiom its' precursor of nitrates. The preparation of Fe1-xNixO3±δ is carried out for a various ratios of Ni/Fe (b/b). To examine its activity, the catalyst was used in a CO2/H2 conversion experiment at different temperatures (100 to 400 oC). The experimental results indicated the dependency of CO2/H2 cnversion on temperature and the highest value for alcohol formation (291.24 ppm) was achieved at 400oC under Ar/CO2/H2 (34/4/12, 50 mL min-1) as a feed. X-ray diffraction examination proved that the erystalline phase is NiFe:O+ spinel structure, whieh is also the major phase and appear stronger as the Ni content in the structure increases. FTIR analysis indicated that both the Lewis acid sites which is located at wave numbers of ±1490 and ±1450 cm-l respectively and Bronsted-Lowry acid sites which is located at wave nurnbers of ±1645 and ± 1622 cm-l respectively, were involved in the catalytic conversion of CO2/H2. As Ni content increased, both acid sites' adsorption shifted to a relative higher wavelength. Furnhermore, NiFe2O4 analysis implied that particles dishibution of NiFe2O4 spine! structure relatively spreads out as Ni content increased. The particle's size of the catalyst is close to ≤50 μm
