Mechanism, Performance, and Application of g-CN-Coupled TiO as an S-Scheme Heterojunction Photocatalyst for the Abatement of Gaseous Benzene.

In this research, S-scheme heterojunction photocatalysts are prepared through the hybridization of nitrogen-rich g-CN with TiO (coded as TCN-(): as the weight ratio of TiO:g-CN). The photocatalytic potential of TCN-() is evaluated against benzene (1-5 ppm) across varying humidity levels using a dynamic flow packed-bed photocatalytic reactor. Among the prepared composites, TCN-(10) exhibits the highest synergy between g-CN and TiO at "" ratio of 10%, showing superior best benzene degradation performance (e.
