摘要：

IR spectroscopic measurements have revealed that an IR band ascribable to adsorbed isocyanate species grows up when alumina-supported Cu-Cs oxide catalyst is exposed to a mixture of NO, O2 and C3H6 at room temperature and subsequently heated to 400-degrees-C in vacuum. The species produces N2, CO2 and CO in the ratio of ca. 2:1:1 in the presence of NO at 350-degrees-C. Alumina and alumina-supported Cu oxide catalyst are less active for the formation of isocyanate species.
