Abstract
The importance of the preparation procedure and the understanding of the me chanisms that control this stage on the final properties of the catalyst an evidenced for PtSn systems obtained via surface organometallic chemistry o n metals (SOMC/M) techniques. The temperature of preparation reaction also plays a fundamental role as regards the nature of the active phase finally obtained, giving rise to catalytic phases having different levels of select ivity to unsaturated alcohols (UOL) in the crotonaldehyde hydrogenation. Or ganobimetallic catalysts lead to very high selectivities to crotyl alcohol (80% at 5% conversion). (C) 2000 Elsevier Science B.V. All rights reserved.
