摘要: Cerium oxides (CeO2) were synthesized by two steps solvothermal routes. First, a precursor was precipitated using solutions of cerium (III) nitrate and ammonia, then this treated via techniques in an autoclave. Narrow distribution CeO2 particle size, between 10 to 15 nm, achieved different solvents. Hard agglomerates nano-CeO2 mitigated ethanol solvent. Most crystal particles the shape quadrangle for precursor. Morphology gradually changed after techniques. There both quadrangular symmetrically hexagonal at alkaline pH value. Alternatively, disappeared, instead geometrically unsymmetrical hexagon with decreasing more acid The evolution mechanism morphology discussed. These results have important implications recognizing controlling crystalline
