Abstract

Ethyl silicate-derived silica gels were synthesized with organic acid and base hydrolysis catalysts. The nature of the organic catalyst was found to strongly affect dry gel structure and carbon content. No consistent relationship between dry gel structure and water content of the calcined gels was identified.
