| Abstract: | In this paper, catalytic materials （Fe203） were prepared, characterization of catalytic materials are tested by XRD, SEM and BET, and the results determine the catalyst for the α-Fe2O3 tripartite rhombus heart crystal. The particle size distribution of the catalyst external shape is more evenly, about 40-50 nm, and its specific surface area is 12.87 m^2/g. Its catalytic performance on synthesis of dimethyl carbonate （DMC） by urea and methanol was studied. The optimal preparation conditions are as follows, the concentration of the used Fe（NO3）3-C2 H5 OH solution is 1 mol/L; the dosage of urea dispersant per 30 ml solution is 1.8 g; adjust the pH value of 5; calcination temperature of 500 ℃ |
