摘要：

The synthesis of Co3O4-free CoAl2O4 was successfully achieved, and it was revealed that this oxide (CoAl2O4) was more active than Al2O3 for NO+O-2 reaction, the initiation step of the selective reduction of NO over cobalt-loaded aluminas, but was less active than Co3O4-containing CoAl2O4 for C2H4+O-2 reaction, a side reaction.
