摘　　要：以硝酸铜、乙酰丙酮铜和NaY分子筛为主要原料,采用分步固相反应法制备出了不同固态反应温度的铜负载量为12%的CuY催化剂。通过红外光谱、扫描电镜和X射线衍射技术对制备的CuY催化剂进行了表征,结果表明制备出的CuY催化剂中负载的铜离子在Y型分子筛上分散均匀。催化活性评价结果表明,分步固相反应法制备的CuY催化剂在甲醇氧化羰基化合成碳酸二甲酯中表现出了良好的催化效果。CuY catalysts with copper loading capacity of 12%at different solid-state reaction temperatures were prepared by step-by-step solid reaction method using copper nitrate,copper acetyl acetone and NaY molecular sieve as the main raw materials.The CuY catalyst was characterized by infrared spectroscopy,scanning electron microscopy and ultraviolet-visible spectroscopy.The results show that the supported copper ions in the prepared CuY catalyst are uniformly dispersed on the Y-type molecular sieve.The results of catalytic activity evaluation show that the CuY catalyst prepared by stepwise solid phase reaction has a good catalytic effect in the carbonylation of methanol to dimethyl carbonate.
