Abstract
The nanoporous $F:SnO_2$ materials have been prepared through the controlled hydrolysis of fluoro(2-methylbutan-2-oxy)di(pentan-2,4-dionato)tin followed by thermal treatment at $400-550^{\circ}C$. The main IR features include resonances at 660, 620 and 540 cm-1. From the TG-DTG result, three main mass losses of 6.5, 13.3 and 3.8 at 81, 289 and $490^{\circ}C$ are observed between 50 and $650^{\circ}C$ yielding a final residue of 76.0%. The size of Sn $O_2$ nanoparticles rose from 5 nm to 10-12 nm as the temperature of thermal treatment is increased from 400 to $550^{\circ}C$.
