Preparation of Hydrated Silicon Dioxide for Reproducible Chemisorption Experiments
High purity fume silica has been treated following the recommended procedure, by heating at 1173 K for 120 h then by boiling in distilled water for 70 h. Finally the wet paste was frozen and liophilized. The resulting light powder, somewhat denser than the starting material, gave reproducible result...
