Magneto-modified catalyst on the base of nanocrystalline CuO

Abstract The weakly oxidized nanocrystalline copper powders of different sizes (average particle size of 30 and 100 nm) were used as the reactants at copper phthalocyanine (PcCu) formation. The nanocrystalline cupric oxide located at the particles surface serves as a heterogeneous magneto-controlled catalyst. A new effect of acceleration of chemical reaction rate controlled by low external steady magnetic field (∼2 kOe) at room temperature was revealed and investigated on an example of formation of a coordination compound of PcCu. The rate of PcCu formation accelerated by 7–8 times after applying of a magnetic field.
