Mesoporous carbons were prepared by steam activation of coals with metal chetate complexes. The activated carbons with mesopores were obtained from Titanium oxide acetylacetonate dispersed on Miike, Taiheiyo or Morwell coal. The specific surface areas and mesopore ratios were evaluated by measuring the nitrogen adsorption isotherms. In addition, the crystal size and the dispersion of TiO_2 on the carbon were obtained by transmission electron microscope and the formation mechanism of mesopores was estimated from these results.
