Ruthenium Based Ammonia Synthesis Catalysts

Ruthenium is mainly used as the wear-resistant of platinum and palladimn in jewel, electrical connector alloy, hydrogenation catalyst, medicine apparatus, anticorrosion alloy, electroplating films, nitrogen fixed reagent and solar cell. Ruthenium oxide is used as coating on the titanium anode plate in the production of nitrogen using electrolysis. 

At the same time, any substance which can promote the above three steps is a good promoter for ruthenium catalysts.

Ruhler et al. considered that Ba-Ru/MgO catalysts have high activities and stabilities. The researchers in Tops Company, Denmark developed series of ruthenium based ammonia synthesis catalysts support on different supports, with electronic and structural promoters. In these studies, the ruthenium catalysts supported on the Mg Al spinel and high surface area graphite show promising activity (see Table 6.6). However, the stability has some problems under industrial conditions. ...
