分别采用均匀共沉淀法、沉积-沉淀法和传统的共沉淀法制备了3种具有相似组成的Cu-ZnO-Al2O3催化剂(CZA-HP, CAZ-DP和CZA-CP)；同时还采用均匀共沉淀法制备了Cu-ZnO催化剂(CZ-HP)以用于比较. X射线衍射表征结果表明,以上方法制备的Cu-Zn-Al碱式碳酸盐前体中Cu2+, Zn2+和Al3+的混合均匀程度的顺序为CZA-DP
Three Cu-ZnO-Al2O3 catalysts with similar compositions were prepared by homogeneous coprecip-itation (CZA-HP), deposition-precipitation (CZA-DP), and conventional coprecipitation (CZA-CP). A Cu-ZnO catalyst was also prepared by homogeneous coprecipitation (CZ-HP) for reference. X-ray diffraction results showed that the degree of mixing of Cu2+, Zn2+, and Al3+ions in the Cu-Zn-Al hy-droxycarbonate precursor followed the order of CZA-DP
