Palladium (0.6% on Activated Carbon, 50% Water-Wet Paste)
NanoSelect LF Catalysts contain 0.5-0.6% of Palladium and are
leadfree. Unimodel metal crystallite sizes of around 7 nm on the support provide
similar activity and selectivity performance characteristics to conventional
Lindlar Catalysts that contain 5 wt% Palladium and Lead. The lead additive is
undesirable as it restricts manufacturing and use due to regulations and
toxicity.
Application of Palladium Catalysts
These catalysts are suited for the selective hydrogenation of alkynes to
alkenes where a high selectivity towards the cis-alkene is being observed.

Increasing Metal Catalytic Activities with Palladium (0.6% on Activated
Carbon, 50% Water-Wet Paste)
The nm-sized metal particles greatly increases the metal surface area and
boosts catalytic activity. The catalyst is recommended for use in hydrogenation
reactions leading to the partial reduction of functional groups. It is
specifically suited for the selective hydrogenation of alkynes to alkenes, with
a high selectivity for cis-alkenes and provides similar activity and selectivity
performance to Lindlar Catalysts.
