) Abstract: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..., and every catalyst prepared by different precursors had an optimal pH values. It indicates that the active metals precursors and their solutions acidities have outstanding influences on the catalysts......
Synthesis of n-Butyl Acetate by Silica Loaded Cerous Sulfate Catalyst蒋柏泉,叶志强,刘贤相,王敏炜,余晓英,张文龙摘 要:Silica was used, as a catalyst carrier, to load cerous sulfate for catalyzing the synthesis of n-butyl acetate. The main purpose of this research was to explore the feasibility of silica in improving the decentrality and activity of the catalyst. The effects......
