제목 Synthesis of nanoporous titania-silica composites via peptization sol-gel method and their photocatalytic properties
초록 Nanoporous titania-silica composites (NTSC) were synthesized via peptization sol-gel method. Titanium hydroxide gel (Ti(OH)4) formed by condensation of titanium oxychloride solution using adequate amount of ammonium hydroxide solution was peptized either in silicic acid (SA) or nitric acid (NA) to form a sol. The composite was characterized by XRD, FTIR, SEM, TEM, TGA, and N2 physisorption studies. Furthermore, a photodegradation of methyl orange in the presence of sunlight indicated that the calcined samples of NTSC-NA-800 had the highest activity due to its superior properties.
