nanotubes, in the hydrogenation of crotonaldehyde have been studied. It has been shown
that the activity of the catalysts depends in an irregular manner on their dimensions and
covers the range (1.6-5.0)∙ 10-6 mol∙ m-2∙ s-1. It has been established that the dependence
of the selectivity of the hydrogenation products on the size of the supported nanoparticles
has an extreme for 6.8 nm nanoparticles.
