The reaction between tetrachlorosilane and 4, 4'-dihydroxydiphenylsulfone with magnesium oxide as a base yielded a three-dimensional alternative silane-O-diphenylsulfonyl hybrid copolymer, of which shapes was sphere with a diameter of 200 nm. The calcination of the copolymer under vacuum gave spherical silica-carbon cluster composite with a diameter of 200 nm, of which average specific surface area was 92.0m<SUP>2</SUP>/g. The treatment of the calcinated product with an aqueous NaOH solution yielded a spherical carbon cluster containing a small amount of silica, of which average specific surface area was 1026.9m<SUP>2</SUP>/g. The alkali-treated composite material absorbed CO<SUB>2</SUB> twice as much as a commercial active carbon. The palladium-loaded alkali-treated composite material absorbed H<SUP>2</SUP> 6 times as much as a commercial active carbon.
