Abstract

The unique value of the Raney® catalyst is revealed through surface modifications that have extended this familiar platform into novel materials with enhanced productivity in practical hydrogenations. The illustrative examples each yielded new compositions through use of non-nickel metals: as efficient dopants (Pd, Pt), as an inexpensive alloy diluent (Fe) and substrate for plating, or as the primary catalyst metal (Raney® Cu) in a recently identified process upgrading a renewable feedstock. A perspective on the surface chemistry of metals links the various approaches.
