Abstract

Nanoparticles of nickel oxide on the surface of macroporous ceramic support were prepared by means of a sol-gel technique. In order to improve the adhesion with a surface of support and prevent the penetration of the catalyst into inner pores, two approaches have been proposed which are deposition of viscous dispersion of Ni hydroxide on the ceramic surface and preliminary formation of polymer layer followed by deposition of NiO particles. It was shown that after the treatment in reductive atmosphere required for formation of metallic Ni catalyst both samples were successfully covered with uniform carbon layer via catalytic chemical vapor deposition (CCVD) of ethylene. Thickness and dispersity of carbon layer were controllably varied by the process parameters. Resulted carbon/ceramic composite materials demonstrated appropriate efficiency in adsorption of benzene used as a model toxic compound.
