Other Mixed Oxides Composite Aerogels

Two kinds of titania aerogels have been discussed pure titania and mixed- or composite oxides. The better photocatalytic activity of titania aerogel was reported already in early 1970s [3]. In order to improve its catalytic activity, addition of other transition metal oxides to titania aerogels, such as vanadia, was discussed [11,12]. Also, composite aerogels with highly adsorbable oxides, silica, and alumina were reported [13-18].
