Photodegradation of Synozol Red HF-6BN on g-C3N4/Halloysite nanocomposites

Hoa Nguyen Thi, Nui Pham Xuan

Abstract


In the research, graphitic carbon nitride (g-C3N4) was synthesized using modified halloysite via a calcination method. The improvement of photocatalytic activity mainly benefits from the reduced e-/h+ pairs recombination rate, the improved electron separation yield. The photocatalytic activity of nanocomposite was evaluated through the Synozol red HF-6BN dye degradation, the degradation efficiency approached 99% after 30 mins irradiation under the solar light, and the performance is slightly reduced to 94 % after three consecutive tests. These results have demonstrated an effective method to synthesize g-C3N4 photocatalysts with nanostructures using crude clay minerals.
