| description | Preliminary saturation of 2.6 nm palladium nanoparticles with hydrogen accelerates the reduction of <i>Fe(CN)</i><sub>6</sub><sup>3−</sup> ions in aqueous solution three to four-fold. An analytical equation was derived describing the hydrogen saturation of palladium nanoparticles and the dependence of their catalytic activity on the hydrogen content in the metal. The specific rate constants of reduction do not depend on the content of palladium nanoparticles in the solution. A change in the temperature and pH or stirring of the solution do not affect the rate of catalytic reaction. Approaches to optimization of palladium-catalyzed reactions involving hydrogen are substantiated. |
