Özet:

 


TiO2 is widely used additive material
in order to improve properties of filtration membranes. As far as its
contribution to filtration performance, TiO2 acts as catalytic
agent.In this study, catalytic activity of TiO2 added PVDF flat
sheets (membranes) prepared by phase inversion method, and they were performed on
benzyl alcohol oxidation at microwave radiation. Structure, thermal behaviors
and morphology of samples were investigated by FTIR, TG-DTA and SEM analysis
respectively. Hydrophilicity was determined by contact angle measurements. Interaction
between TiO2and PVDF chain was
evidenced. TiO2 added PVDF membranes had improved filtration and
rejection performance. 32.4% BSA rejection was obtained with composites while
it was 7.5% of pristine membrane. 93.86% conversion and 56% selectivity were
obtained with composites in microwave-assisted batch reactor. Decomposition of polymer increased when 6% additive due
to catalytic effect of TiO2 then, it decreased with further loading.Detailed
evidences were obtained by activation energies (Ea) of decomposition
calculated by Kissinger method. Microwave-assisted catalytic effect of TiO2inside
polymeric matrix promise to obtain fast, high yielded and disposable membrane
materials for catalytic reactors to in-situ production of fine chemicals.
