Surface| Zusammenfassung: | By two-step method, including grinding of the phenol-formaldehyde resin with nickel acetate in the ball mill with further pyrolysis of the mixture in the argon atmosphere, carbon composites with nickel nanocrystallines (27-65 wt%) have been synthesized. It was established that the phase composition of the samples consists of amorphous carbon, impurities of graphite crystallines and nanoparticles of nickel crystallines (12 nm). The adsorption of the methylene blue was studied. It has been shown that the adsorption properties of the nanocomposites increases with increasing content of carbon in the samples. The stability of the nickel nanoparticles and the decreasing adsorption capacity after the hydrothermal treatment for 2 hours were determined. |
