Abstract
Air-stable new carbon composites containing uniformly dispersed ultrafine Fe, Co, Ni, Ru, Pd, Rh, or Ag particles were obtained by thermal degradation of coal pitches mixed homogeneously with 1–10% of poly(vinyl ferrocene), cobaltocene, nickelocene, (acenaphthylene) Ru3(CO)7, PdCl2(COD), RhCp(COD), and AgC6H4CH2NMe2, respectively, at 400–1200°C in Ar. Carbonization yields are 45–55% and the size of metal particles varied from 5 to 65 nm depending upon the treatment temperature and identity of the metal. The carbon composites containing Fe particles showed high Vicat hardness and good electrical conductivity. Pd- and Rh-dispersed materials exhibited good catalysis in hydrogenation of 1-hexene. The composite containing ultrafine Ag particles showed excellent bacteriostatic activity forEscherichia coli, Pseudomonas aeruginosa, andBatchillus subtilis.
