Abstract

A caesium-promoted ruthenium catalyst supported on nanocrystalline magnesia with high activity for ammonia synthesis was conveniently prepared by using hydrated ruthenium trichloride and hexahydrate magnesium nitrate as precursors, whereas dechlorination post-treatment and ready-made magnesia were not necessary.

摘要

以三水合氯化钌和六水合硝酸镁为前驱体，简便地制备了负载在纳米氧化镁上的铯促进的钌催化剂，该催化剂对氨合成具有高活性，而无需进行脱氯后处理和使用现成的氧化镁。
