Popis:	Various zirconia were prepared from ZrOCl2·8H2O by the addition of aqueous ammonia and potassium hydroxide; the effect of the catalyst preparation on the oxidative coupling of methane over zirconia was studied. The selectivity to such C2 compounds as ethylene and ethane was strongly influenced by the pH of the preparative solution of ZrOCl2·8H2O, NH3 aq, and KOH, as well as the sequence of the addition of each hydroxide during the preparation of the catalyst.
