Effects of Molar Ratio on the Synthesis and Characterization Nanocluster TiO2-SiO2 with Induced Copolymer Chitosan by Sol - Gel.

Nanocluster synthesis of TiO2-SiO2 with induced copolymer chitosan can be done through the process of hydrolysis and condensation with the sol-gel method. This study aims to optimize the synthesis process, dispersion, and surface functionalization of titanium dioxide that will be applied as a photocatalyst. Chitosan is a copolymer compound having a functional group -OH and -NH2 that can facilitate the dispersion of TiO2 on SiO2 surface in order to obtain nanocluster TiO2-SiO2, evenly distributed, anatase structure. Product nanocluster TiO2-SiO2 powder, from the results of FT-IR characterization provided information that there stretching and bending vibrations of the interaction of Ti-O-Si in the fingerprint region 1100-950 cm -1 .
