Bromine-promoted PtZn is very effective for the chemoselective hydrogenation …

Abstract. The phase pure, unsupported intermetallic compound PtZn is intrinsically active and selective for chemoselective hydrogenation of crotonaldehyde to crotyl alcohol in the absence of any support effects or auxiliary phases. During un-promoted reaction conditions, the PtZn surface becomes platinum enriched within the XPS sampling depth with respect to the 1:1 bulk stoichiometry. Cata…
