TiO2/β-SiC foam-structured photoreactor for continuous wastewater treatment.

Introduction This study of photocatalytic degradation of wastewater was carried out in alveolar cell β-SiC foam-structured photocatalytic reactors working in a recirculation mode. The immobilization of TiO2 on β-SiC foams was efficiently obtained through a sol–gel technique in acidic conditions.
