- Аннотация: Carbonyl palladium blacks are formed on treatment of Pd(II) chloride complex in a solution with carbon monoxide at ambient pressure and a temperature >= 20 degrees C. The results of IR spectroscopy, powder X-ray diffraction, and electron microscopy demonstrated that carbonyl palladium blacks are heterogeneous unstable systems consisting of palladium, carbon, and oxygen, the ratio of which changes upon heat treatment. Palladium is present as the metal, the carbonyl cluster Pd-x(CO)(y), and the variable-composition PdCx phase, while carbon partly occurs as amorphous diamond with sp(3) hybridization of atoms. After calcination of Pd black at 1000 degrees C, a large amount of carbon remains in the resulting Pd sponge, which acquires abrasive properties. Dissolution of the sponge in aqua regia leaves a solid phase with a high carbon content
