Synergistic degradation of acid orange 7 dye by using non-thermal plasma and g-CN/TiO: Performance, degradation pathways and catalytic mechanism.

In order to harness the full capability of ultraviolet and visible light in the dielectric barrier discharge induced non-thermal plasma (DBD-NTP) process, g-CN/TiO catalysts were prepared and utilized in this process. Synergistic degradation of acid orange 7 (AO7) dye by DBD-NTP and g-CN/TiO was conducted, and the performance, degradation pathways and synergistic catalytic mechanism were investigated. The results showed that the degradation rate of AO7 in the DBD-NTP and g-CN-15/TiO process increased by 39.
