Chemical Etching Route to Prepare Nanometer-size Spherical Titania-Octadecylamine Hybrid Particles

摘要

Spherical titania-octadecylamine hybrids (tens of nm to hundreds of nm) were obtained by the dissolution of presynthesized well-defined spherical particles with different size (70, 120, and 240 nm). The dissolution proceeds homo-genously to give well-defined and size-controlled products when the reaction is conducted at room temperature in methanol.
