Designing Highly Enantioselective Heterogeneous Pt Catalysts: Selective Exposure of Active Sites via Surface Modification Using Amines

Byeongju Song,

et al.

Abstract: Surface modification of metal nanoparticles (NPs) with organic molecules has attracted considerable attention as an effective methodology for designing highly selective heterogeneous catalysts. In this paper, we propose a simple post-treatment strategy involving the mixing of bare Pt/Al 2 O 3 with amines and subsequent heat treatment for preparing highly enantioselective heterogeneous catalysts for the hydrogenation of α-keto esters. Notably, treating the Pt catalyst with oleylamine (OAm) yielded a catalyst po… Show more
