Palladium (0.5% on Titanium Silicate, 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.

Key Properties of Palladium (0.5% on Titanium Silicate, 50% Water-Wet Paste)

The physical and chemical properties of palladium nanoparticles are outlined in the following:

Note: Lead-free, water-wet, catalyst containing metal crystallite sizes of ~7 nm, and a mean particle size of 25 microns supported on titanium silicate powder.

Increasing Metal Catalytic Activities with Palladium (0.5% on Titanium Silicate, 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 Catalyst.
