【 摘 要 】

Citric acid is an organic acid catalyst and content carbon that is templated into silica network. The mixture between these materials is gratefully useful to tailor pore size of silica-carbon mixtures in the form of silica-carbon sols which robust and good hydrostability properties. This fabricated materials is applied for coated membrane layers (thin film) coated onto membrane substrates for water desalination. This study was aimed to utilize sol gel process to synthesize the functionalization of organic catalyst in silica matrices. Silica xerogels was prepared from TEOS (Tetraethyl orthosilicate) with a two-step organic acid and base catalyst via sol gel method. The hydrolysis and condensation reactions were applied within 3 hours at 50 °C. IR spectra shows that.
