TiO2 nanomaterials have been synthesized with the solgel method from hydrolysis of a titanium precusor¡£ This process normally proceeds via an acid-catalyzed hydrolysis step of titanium(IV) alkoxide followed by condensation¡£ Closely packed firstorder particles are yielded via a three-dimensionally developed gel skeleton¡£ From the study on the growth kinetics of TiO2 nanoparticles in aqueous solution using titanium tetraisopropoxide (TTIP) as precursor¡£ Secondary particles are formed by epitaxial self-assembly of primary particles at longer times and higher temperatures¡£ in agreement with the Lifshitz-SlyozovWagner model for coarsening¡£ ÇëÎÊÕ⼸¾ä»°Ôõô·Òë |
