The aim of the present work is a structural characterization study of silicaincorporated copper-oxide (CuO-SiO 2 ) catalysts using HRTEM. The catalysts were prepared by the sol-gel synthetic route. Two calcined catalysts (at 400Β°C and 800Β°C, respectively) were analyzed before and after the ''NO x Ο©
It is shown that the oxidation of an Asturian bituminous coal by air, at 150" and 27O"C, has a considerable influence on the microporous structure of the carbon obtained by subsequent carbonization and steam activation to 50% burn-off. The direct activation of the coal leads to an open micropore sy
