Nanosize Effect in Heterogeneous Catalytic Processes Over Copper, Iron, and Zirconium Oxides

Abstract

A summary is given of the results of studies of the catalytic properties of nanophase systems derived from copper, iron, and zirconium oxides in the ethanol steam reforming, the oxidation of carbon monoxide, the preferential oxidation of CO in the presence of excess hydrogen, the oxidation of benzyl alcohol, and the cracking of triglycerides. A relationship was found between the catalytic activity of copper, iron, and zirconium oxides and the size of their nanoparticles. The reasons for the nanophase effect in these processes were elucidated for a number of systems.
