摘　　要：研究了焙烧对物理法制备的纳米铜催化剂的影响规律。结果表明，焙烧不同程度地降低纳米钢催化剂的活性，高温焙烧时生成了 ＣｕＡｌ２Ｏ４，纳米钢粒子在载体上的分散度影响焙烧后催化剂活性的变化。Calcination pretreatment of nanometer copper catalysts prepared by physical method was studied. The results showed that calcination pretreatment more or less lowered the catalytic activities of nanometer copper catalysts. CuAl2O4 was formed after calcination at high temperature. The dispersion of nanometer copper particles on support alumina had an effect on catalytic activities after calcination.
