Organic pollutants, such as dyes and natural organic matter (NOM), are harmful to the environment and humans due to their toxicity and the difficulty of their removal from wastewater. Titania (TiO2) and other heterogeneous photocatalysts has been found useful in the degradation of these pollutants. In order to create a practical structure that can be utilized for such an application, a ceramic syntactic foam consisting of glass microballoons (GMBs) and titania or silica nanofibers (NFs) with titania binder was synthesized. The mechanical strength, phase composition, and microstructure of the composite material were analyzed. It was determined that the addition of nanofibers improves the thermal behavior and mechanical strength of the composite material during and after processing. The composite materials were stable up to approximately 750°C without deformation or changes in crystalline structure. Strong nanofiber-GMB interactions were noted with titania NFs, while a weaker interaction was seen with silica NFs.
