Abstract
The selective hydrogenation of alkynes is an important reaction in the synthesis of fine and bulk chemicals. We show that the synthesis of metal nanoparticles in the gas phase, followed by depositi...
Highlights
The selective hydrogenation of a range of substrates is a key technology in both the bulk and fine chemicals industries [1]
We have previously reported the good performance of a palladium catalyst prepared by gas-phase cluster deposition onto a flat graphite tape as a catalyst for the selective hydrogenation of 1pentyne [20], and we have observed changes in the atomic structure of size-selected palladium nanoparticles during this reaction [21]
Palladium was deposited on two conventional support powders to make representative catalysts for the vapor-phase selective hydrogenation of 1-pentyne to 1-pentene
Summary
The selective hydrogenation of a range of substrates is a key technology in both the bulk and fine chemicals industries [1] In both contexts, selectivity to the desired product is usually a key attribute: loss of reagent to the formation of undesired products is economically undesirable and can lead to challenges in separation downstream. Selectivity to the desired product is usually a key attribute: loss of reagent to the formation of undesired products is economically undesirable and can lead to challenges in separation downstream This means that there is a pressing need for more selective catalysts and processes for a range of selective hydrogenation reactions. There is good reason for this: they are reliable, economic, and can be performed at the necessary scale for commercial use They are not always able to produce materials that are truly optimized
