Abstract |
AB |
[EN] The present invention relates to hydrotalcite-like compounds, wherein Pd 2+ occupies at least part of the octrahedral sites in the brucite-like layers. According to another aspect, the invention is concerned with methods of converting these hydrotalcite-like compounds into materials comprising particles, in particular nanoparticles, of an ordered intermetallic compound of palladium and at least one constituent metal of the palladium-modified hydrotalcites. Moreover, the invention pertains to the material obtainable by the conversion method, the use of the material as a catalyst, and a process for the selective hydrogenation of alkyne(s) to the corresponding alkene(s) using the material as a hydrogenation catalyst. |
