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。
The influence of calcination on the nano-copper catalyst prepared by physical method was studied. The results show that the activity of the nano-sized steel catalyst is reduced by roasting to different extents, and CuAl2O4 is formed when calcined at high temperature. The dispersion degree of the nano-sized steel particles on the carrier influences the change of the catalyst activity after roasting.
