ABSTRAK BAHASA INGGRIS

In this study, nano catalyst Ni0,6Fe2Co0,4O4 has been prepared by sol gel ? freeze dry method using pectin as an emulsifying agent, and then the sample was subjected to calcination treatment and subsequently characterized using the techniques of X-ray diffraction (XRD), Rietveld and Scherrer Methods, FTIR, PSA and SEM analysis. Its catalytic activity was tested for CO2/H2 conversion to alcohol at a temperature of 200 - 400?C. The results of XRD characterization indicated that Ni0,6Fe2Co0,4O4 calcined at 600?C materials consist of three crystalline phases which are Fe2NiO4(25.3\%), Fe3O4 (51.5\%), and CoFe2O4 (23.2\%). The results of size analysis using both Scherrer method and SEM show that the size of the catalyst is in the range of 11,8 ? 22,0 nm. Then, particle size analyzer (PSA) proved that particle size distribution is in the range of 0-2\%. Catalytic activity tests showed that Ni0,6Fe2Co0,4O4 nanocatalysts are active. Product analysis using gas chromatography indicates that the Ni0,6Fe2Co0,4O4 nanocatalyst calcined at 600?C is the most active for conversion of CO2/H2 at a reaction temperature of 200 ?C and propanol yield is 53134.83 ppm.
