Study of MWCNT Dispersion Effect in TiO2-MWCNT Composites for Gas-Phase Propene Photooxidation

We have performed the synthesis of TiO2-MWCNT composites focusing on distribution photoactive phase carbon active sites existing in MWCNTs, and its effect properties for abatement propene. used different approaches dispersion MWCNTs during synthesis; 1) an ultrasound bath 5 minutes, 2) 60 3) probe min. observed that incorporation TiO2 improves catalytic activity photooxidation propene, but best results are obtained treatment. A good MWCNT increase surface area or oxygen functionalities key factors to achieve improved photocatalytic total propene oxidation, thus benefitting from synergy between MWCNT.
