Abstract
In this article, we will present the synthesis of bimetallic Ni-based catalysts aiming to perform selective hydrogenation. First a parent catalyst constituted of small nickel particles supported on silica with very narrow size distribution around 3.5 nm, has been prepared. Then controlled modification by site, using the SOMC/M route described by Candy et al. 1994 and organometallic compounds of Sn and Zr, allows to explore both the geometric and electronic effects in the selective hydrogenation of styrene into ethylbenzene.
