Abstract

Core-shell structures were prepared using silica from Lapindo mud extract. The XRD results showed that the extracted silica contains γ-Al₂O₃ and NaAlSi₃O₈. Besides, the FT-IR, Raman spectroscopy, and FE-SEM analyses showed that the core particles were not finely covered by the shell. BET measurement indicated that high surface areas are attainable for core-shell structures addition into TiO₂ nanoparticles. TiO₂/TiO₂@SiO₂ core-shell structure has 161.100 m²/g and 0.311 cc/g of surface area and pore volume, respectively. Whereas, TiO₂/SiO₂@TiO₂ core-shell structure has surface area of 140.200 m²/g and pore volume of 0.292 cc/g.
