Abstract
A process for producing a zirconium oxide precursor comprising precipitating a zirconium oxide precursor from an alcoholic solution of a zirconium compound, and a process for producing zirconium oxide having infrared absorption peaks assigned to an S—O bond between 1010 cm and 1025 cm and between 1035 cm and 1050 cm , which comprises heat treating the zirconium oxide precursor prepared by the above process. The zirconium oxide precursor and the zirconium oxide obtained in the process are effective as a catalyst for removing or decomposing nitrogen oxides.
