Resorcinol-formaldehyde (RF) polymer gels offer a relatively easy and
versatile route for incorporating metals into a carbon aerogel matrix.
The hybrid materials thus obtained are ideal candidates for applications
involving enhanced adsorption or catalysis. This paper presents a detailed
study of Ti-doped RF and carbon aerogels. The metal was introduced into
the system at three different stages of the preparation process: during
polymerization, by impregnation of the RF gel, or by impregnation of the
carbon gel. The structure and morphology of the samples are compared
using low temperature N2 adsorption, SEM, and small and wide angle
X-Ray scattering (SAXS/WAXS) methods. The TiO2-doped carbon aerogels
display photocatalytic activity in breaking down aromatic compounds.
