摘　　要：The development of effective Ru catalyst for ammonia synthesis is of important practical value and scientific significance because of the wide application of ammonia as a fertilizer and its promising applications in the renewable energy.Generally,ZrO_(2) was regarded as an inferior support for Ru catalyst used in ammonia synthesis.Here we prepare ZrO_(2) with monoclinic phase and carbon species from ZrCl_(4) following the preparation route of UiO-66 as well as ammonia treatment.Owing to the presence of a larger amount of hydrogen adsorption as well as the easier desorption of hydrogen species,the ill effect of hydrogen species on the nitrogen adsorption-desorption and ammonia synthesis can be effectively alleviated.The resulting ZrO_(2)-supported Ru catalyst showed 4 times higher ammonia synthesis activity than the conventional Ru/ZrO_(2) obtained from zirconium nitrate.
