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.
