Silica synthesis via sol-gel with organic acids used as catalysts

  • Tessy Lopez


Silica gel was synthesized from tetraethoxysilane at pH 5 with oxalic acid as hydrolysis catalyst to study pregelation stage by means of an FT IR spectrophotometer.

Силикагель синтезировали из тетраэтоксисилана при pH=5 в присутствии щавелевой кислоты как катализатора гидролиза. Стадию, предшествующую гелеобразованию, исследовали с помощью ИК-фурье спектроскопии.
