Abstract

TiO2-SiO2 aerogel with various TiO2 contents was successfully deposited into a microchannel. SEM, XPS and liquid-phase photocatalytic oxidation reaction of phenol were used to examine the TiO2-SiO2 aerogel's microstructure and reactivity. The TiO2 content has a significant effect on the aerogel network and its adhesion on the microchannel. High open and cross-linking or ordered macroporous structure can be formed in TiO2-SiO2 aerogels with lower TiO2 content (5wt% or 10wt%). The conversion of phenol is around 36.6% during the reaction when this aerogel incorporated microchannel is used as microreactor.
