Influences of Platinum Precursors and Solution Acidities on REO-Based Catalysts Performances张爱敏,宁平摘 要:<正>Important effects exist between precious metals and rare earths oxides in three-way catalyst, especially the coordinated effects. These effects were studied by using H2PtCl6, Pt(NH3)2(NO2)2 and Pt(OH)2(C2H5ONH2)2 as Pt precursors, and the mixed......

and palladium concentrate. Therefore, the separation of selenium and tellurium from platinum and palladium concentrate is important for the enrichment and recovery of precious metals. Thermodynamic analysis... rates of selenium and tellurium are 82.49% and 92.45%, respectively, while the gold, platinum and palladium are not leached out. The precious metals are enriched, and its total content is 23.18......
