摘要: The effect of parameters, such as initial cerium concentration and alkali or alkaline earth in the reactant solution on properties precipitated ceria, have been investigated by nitrogen adsorption isotherm analysis, FTIR spectroscopy X- ray powder diffraction. Increasing has a negative surface especially calcined samples. Addition ions leads to gradual lessening specific area; is strongly depended ionic potential guest ion. Co-precipitation magnesium formation separate magnesia solid phases within ceria mesopores resulting an anomalous behaviour ceria. calcium results homogeneous Ca-Ce mixed oxides with content oxide. In contrast co-precipitation, using incipient wetness method oxide phase mesopores.
