In the case of wastewater treatment, many researche’s are mainly focused on nanopowder-type photocatalysts that have high efficiency because of their good dispersibility and high specific surface area. Ironically, these properties of nanopowder photocatalysts cause some drawbacks in their recovery from treated water, making practical applications in wastewater treatment difficult. The use of a three dimensional based-ceramic fiber as a substrate and graphitic carbon nitride (g-C3N4) as a visible-light-driven photocatalyst can be a promising approach to overcome the above-mentioned limitations. This study describes the immobilization of g-C3N4 on ceramic fiber using a facile co-calcination method and verifies its photodegradation activity under visible light. The recovery efficiency, physicochemical stability of samples, and the potential of the practical application of wastewater treatment were tested with organic dye decomposition experiments under visible light irradiation.
