Based on scanning electron microscopy (SEM) image analysis,  the mean diameter of the nanofibers was measured to be  ~ 55 nm. Fourier transform infrared (FTIR) spectroscopy  confirmed the presence of ZnO and g-C₃N₄in the prepared nanofibers. The photocatalytic activity of the nanofibers was examined under UV photoirradiation, showing  that the ZCN0.5 nanofibers containing 0.5 wt% of g-C₃N₄exhibited the highest performance, as compared to other photocatalysts. The observed improvement in photodegradation over the optimized photocatalyst could  be due to retardation in the  charge carriers’ recombination rate in the ZCN0.5 photocatalyst sample,  as compared with the pure ZnO and pure g-C₃N₄.
