The catalytic properties of metal nanoparticles of the 1B group (Cu, Ag, Au) in the reaction of low-temperature ortho-vapor conversion of hydrogen are investigated. It is shown that, upon transition to nanoscale particles, inert bulk metals adsorb hydrogen at low temperatures and become active in the reaction of the conversion of hydrogen modifications. Among the metals studied, gold nanoparticles have the highest specific catalytic activity. Conversion occurs on all ortho-vapor nanoparticles by the physical magnetic mechanism, which indicates the presence of magnetic properties of copper, silver, and gold nanoparticles.
