A silica gel was esterified with alcohols and reacted with carbon tetrachloride to cross-link the \(R \mathrm{O}-(R\), alkyl or arylalkyl) groups on the silica surface. These esterified and cross-linked silica gels were subsequently pyrolyzed under vacuum to yield carboncoated silica gels (CSG). The

Carbon/silica (carbosil) samples prepared utilizing mesoporous silica gel (Si-60) modified by methylene chloride pyrolysis were studied by nitrogen adsorption, quasi-isothermal thermogravimetry, p-nitrophenol adsorption from aqueous solution, and 1 H NMR methods. The structural characteristics and o
Reactions of bis(cyclopentadienyl)titanium dichloride, bis(cyclopentadienyl)zirconium dichloride, and bis(cyclopentadienyl)hafnium dichloride with premodified silica gel surfaces were studied. The silica gel surface was pretreated to selectively eliminate nonhydrogen bonded silanols, hydrogen bonded
